Thank you for purchasing A&D’s GX-L/GF-L series high-capacity electronic balance.
Please read this instruction manual carefully to understand and make full use of the balance before using it.

1-1. Features
The balance has a self-check function that inspects the balance itself using electronically controlled load
(ECL) and evaluates repeatability performance.
The balance can detect the impact applied to its mass sensor, and display and store the impact level.
Impact Shock Detection (ISD)
Continuous weight change can be calculated, displayed, and output as flow rate.
Flow Rate Display (FRD)
Equipped with a data memory function to store weighing values, sensitivity adjustment records, and multiple
unit weights (mass per sample in counting mode). (For weighing values, up to 200 values can be stored.)
The GX-L series has automatic self sensitivity adjustment function using the internal weight, adapting totemperature changes, setting time and interval time.
When performing the sensitivity adjustment/calibration test, etc. for the balance, the output corresponding
to GLP/GMP, etc. can be output.
Using a printer (sold separately), it is possible to record the sensitivity adjustment/calibration test results.
GLP: Good Laboratory Practice. Standards for implementing safety tests for drugs and medicines.
GMP: Good Manufacturing Practice. Rules for manufacturing and quality control.
The clock function built into the balance allows you to output the weighing value with the date and time.
(The clock settings can be restricted so that only the Administrator can change them. [Password function])
Comparing the weighing value and the preset upper/lower limit value, the comparator Indicators can display
the comparison results with the

HI

/

OK

/

LO

indicator. (5-step comparison setting is alsoavailable.)
Capacity Indicator displaying the weight value in percentage relative to the weighing capacity.
Hold Function is provided for weighing a moving object such as an animal.
For measuring density or weighing magnetic materials, the optional GP-20/21 underhook can be used.
With the password function, the use of the balance and the operation of changing the function table can be
restricted.
With the key lock function, the key operation can be disabled and the balance can be operated only by acommand from an external device.
RS-232C and USB interfaces for outputting the weighing value and data of the balance are equipped as
standard. Windows Communication Tools Software (WinCT) makes it easy to communicate with a Windows
personal computer. The latest version of WinCT is available for download on A&D website.

The GX-L series is equipped with the internal weight for sensitivity adjustment. You can use functions
such as sensitivity adjustment using the internal weight and automatic sensitivity adjustment.
The GF-L series does not have a built-in weight for sensitivity adjustment. When performing sensitivity
adjustment, it is necessary to prepare a calibration weight separately.
Two types of structures are available: “Swing-arm type” and “Separate type”.
The swing-arm type has a display unit attached to the main unit with a swing arm, which allows you toadjust the position of the display unit up or down.
The separate type has a display unit connected to the main unit with a detachable cable.

122-2. Precautions before use (Installation considerations and preparation)
Prepare the following installation conditions in order to bring out the full performance of the balance.
This product is a high precision balance with a maximum resolution of 1/600,000. The balance tends to besusceptible to temperature changes, pressure fluctuations, vibration, drafts, and other factors at the
installation site. In particular, during sensitivity adjustment with the internal weight, a weighing value that is
one digit smaller than the readability of the balance is read, so be careful of the above error factors andperform weighing operations in a stable environment.
The best operating temperature is about 20°C ±2°C at about 45% to 60% RH relative humidity.
Install the balance where it is free of dust.
Place the balance on a solid, flat floor. (Do not install on a soft floor.)
The weighing table should be solid. (An anti-vibration table or stone table is ideal.)
Make sure there is no tilt in the installation location.
Install the balance in a stable location, avoiding vibration and shock. Corners of rooms on the first floor ofa building, i.e., the floor which is level with the ground, are best as they are less prone to vibration.
Install the balance where it is not affected by heating, ventilation, air conditioning units and the like; avoid
breezes and drafts in the room.
Avoid locations in direct sunlight.
Install the balance away from equipment which produces magnetic
fields.
Level the balance by adjusting the leveling feet so that the bubbleof the bubble spirit level is centered in the circle.
Be sure to warm up the balance by providing power using the AC

adapter (connected to a power supply) for at least half an hour
before use.
For preparation before use when installed for the first time or its
location is changed, the balance should be provided with power

Adjustment / Calibration Test”.
The balance’s dustproof and drip-proof rating is equivalent to IP65, and its second digit, “5”, corresponds
to "having no harmful influence by receiving direct jet of water". Washing with strong water pressure,washing with the weighing pan removed, or submersion in water may cause water to enter the balance,
resulting in a malfunction.
When installing and using the balance under conditions requiring dustproof and drip-proof performance,
make sure that the weighing pan is installed on the main unit, that the cable for connecting the main unit
and display unit is attached (for separate type models), that the AC adapter plug is fully inserted into the
AC adapter jack, that the terminal cover is attached to the RS-232C interface or a waterproof RS-232C
cable (AX-KO2737-500) is used, and that the USB waterproof cover cap is attached or the USB connector
is firmly inserted.
When cleaning with hot water, condensation may occur inside the balance and the balance parts may
deteriorate. Also, be careful not to let water vapor get inside the balance.
If the weighing pan or RS-232C terminal cover is removed or a waterproof RS-232C cable (AX-KO2737500) is not used, protection against dustproof and water is not provided.
Errors due to moving the weighing system:
The performance of this product is guaranteed when it is used in a stationary condition. If the balance isincorporated into a system that moves the balance, you must carefully perform checks in advance while
paying attention to the following.
13



If the balance is moved, it may be damaged by impact shocks. In addition, the weighing value will be
unstable immediately after the balance is moved. Avoid sudden movements, stops, or impact shocks,
and provide a sufficient waiting time for the weighing value to stabilize when acquiring weighing data.

The moving device should have a structure where the balance can be kept level. If the level is shifted,
the zero point or sensitivity will be shifted, so perform

ZERO

/

TARE

key operation or sensitivity

adjustment.
In order to avoid the influence of vibration, the moving platform should have a structure not easily
susceptible to vibration by means such as reducing the play of moving parts.

CAUTION

Use the dedicated AC adapter specified for the balance.
Confirm that the AC adapter type is correct for your local voltage and receptacle type.
Do not use the AC adapter provided with the balance for other models or equipment.
Do not install the balance where flammable or corrosive gas is present.

14

2-3. Precautions during use (for more accurate weighing)
For precise and accurate weighing, please take notice of the following.

Metal case

Weighing errors may occur due to the influence of static
electricity. Note that if the ambient humidity drops below 45 %RH,
insulators such as plastics are liable to have static electricity.

Charged sample

Please take the following actions as necessary. Also, ensure to
ground the balance using the ground terminal. For details, referto "2-1. Assembly and installation".


GroundUse the AD-1683A ionizer (sold separately) to remove static
electricity from the charged sample directly.



Increase the relative humidity at the place where the balance isinstalled.



Weigh the sample in a conductive metal container or the like.



Wipe off charged materials such as plastic with a damp cloth toMagnetic material

suppress static electricity.
Influence of magnetism may cause weighing errors. Whenmeasuring magnetic materials (iron, etc.), keep the sample awayfrom the balance main body by means such as underhook

Convection

weighing.
Weighing pan

Weighing errors may occur if there is a difference between theambient temperature and temperature of the sample (and thecontainer). For example, when the room temperature is 20 °C,
convection occurs around a flask that is 40 °C and the balancedisplays a value lighter than the actual weight. Before weighing thesample and the container, try to acclimatize them to the ambient
temperature.
Performtheweighing

operation carefully

andNo impact
shock

quickly. If

measurement takes a long time, error-inducing factors will increase
due to changes in temperature and humidity in the weighingchamber, air turbulence or reaction/humidity absorption by the
sample.
When placing a sample on the weighing pan, do not drop it, or do
not place a sample greater than the balance weighing capacity.
Place the sample in the center of the weighing pan.

Good

When pressing keys, do not press with a sharp object such as apen. Instead, press the center of the key with your finger.
Be sure to press theZERO

key orTARE

key before

weighing in order to eliminate measurement errors.
Measurement results include error from air buoyancy. The
buoyancy of air varies depending on the sample volume,
atmospheric pressure, temperature, and humidity. Correct thebuoyancy for the most precise measurement.
Prevent foreign substances such as powder, liquid, and metal pieces
from entering the balance.

15

Bad

2-4. Cautions after use
Avoid mechanical shock to the balance.
Do not disassemble the balance. Prevent foreign substances such as powder, liquid and metal pieces fromentering the balance.
Do not use any strong organic solvents to clean the balance. Clean the balance with a lint free cloth that ismoistened with a mild detergent.
The weighing pan can be removed for easy cleaning around the pan.
When the weighing pan is removed, the air-permeable filters for pressure relief are exposed. Do not get
the air-permeable filters wet.
Do not allow the balance to be immersed in water. Even though the balance complies with IP65 (Dust-tightand Protected Against Water Jets), the balance will not withstand being completely immersed in water.

16

2-5. Caution on the power supply
Do not remove the AC adapter while the internal weight is in motion, for example, right after the AC adapter
is connected, or during sensitivity adjustment using the internal weight. If the AC adapter is removed under
the conditions described above, the internal weight will be left unsecured, that may cause mechanicaldamage when the balance is moved. Before removing the AC adapter, press the

ON:OFF

key andconfirm that zero is displayed.
The balance is constantly provided with power as long as the AC adapter (connected to a power supply) isconnected.
The balance is not adversely affected in this state.
It is advisable to always keep the balance in this state for accurate weighing.

314-3. Counting mode (PCS)This is the mode to determine the number of objects in a sample. Based on the reference sample unit weight(weight per piece), the balance calculates and displays how many pieces the sample weight corresponds to.
The smaller the variation in the unit weight of sample pieces is, the more accurate the count will be. Thebalance is equipped with the Automatic Counting Accuracy Improvement (ACAI) function to improve thecounting accuracy.
It is recommended that the unit weight (weight per piece) of the sample should be at least 10 times thegram readability of the balance.
If there is a large variation in the unit weight of sample pieces, it may not be possible to count accurately.
If a significant counting error occurs, try a method such as performing ACAI function frequently or dividing
the sample and counting several times.

5. Impact Shock Detection (ISD) Function
The GX-L/GF-L series has a function to detect impact shocks to the mass sensor section and to display the
impact level.
By lowering the impact level at the time of loading, it is possible not only to alleviate variation in the weighing
value but also to reduce the risk of failure of the mass sensor section.
Especially when incorporating the balance in a production line, etc. and weighing by means such as an
automated system, impact to the sensor may be applied greater than expected. When designing automatic
systems and the like, it is recommended that you minimize the impact level as much as possible while checking
the shock indicator.
The shock indicator has 5 levels from level 0 to level 4.

Even if the impact shock detection function is turned off, a record is kept in the balance when there is a shock
impact.

Caution
Impact on the weighing sensor is not only that applied to the weighing pan when loaded, but also may be
impact applied from the table on which the balance is installed. The impact detection function also works
for impact coming from the table.

5-1. Recording impact history
Impacts of impact level 3 or higher are stored on the balance with data and time (up to 50 instances).
When the password lock function is ON (or), the login user information is added when outputting

the impact history.

CautionIf data instances exceed 50, the stored data with the lowest impact level will be overwritten.
The stored impact history cannot be deleted.
Impact data where the balance is not provided with power (during transport, etc.) is not stored.

7. Sensitivity Adjustment / Calibration Test
Since the balance resolution is high, its weighing values may change due to gravity and day-to-day
environmental changes. It is necessary to perform sensitivity adjustment using a weight to keep the weighing
values from changing even if gravity or the environment changes.
It is advisable to perform sensitivity adjustment when the balance is installed for the first time or relocated, orwhen the weighing values in daily inspection and the like have deviated significantly.
Sensitivity adjustment means adjusting the balance with a reference weight or the internal weight to ensure
accurate weighing.
Calibration test means weighing a reference weight with the balance to compare how much the result deviatesfrom the reference value. (Note that no sensitivity adjustment is performed in calibration test.)

Sensitivity adjustment
Automatic sensitivity adjustment ------------------------ Automatically adjusts the balance using the internal
weight according to ambient temperature change/interval
time. (GX-L series)
Sensitivity adjustment using the internal weight ----- Adjusts the balance using the internal weight with one key
press.
Sensitivity adjustment using an external weight ----- Adjusts the balance using an external weight.

Calibration test
Calibration test using an external weight -------------- Outputs the result of the weighing accuracy check using
an external weight.
Note that no sensitivity adjustment is performed.

Cautions on sensitivity adjustment
Do not allow vibration or drafts to affect the balance during sensitivity adjustment.
When outputting a report compliant with GLP, GMP, etc. during sensitivity adjustment:
To output a report compliant with GLP, GMP, etc., "GLP output (()" must be set with "Data output)" in the function table. GLP output requires a PC or optional printer. For GLP output, the balance's

clock function will output the date and time. Refer to “9-4. Clock and calendar function” in “9. Function Table”
and set the clock if the date and time are not correct.
Note that the calibration test function is available only when output of a report compliant with GLP, GMP,
etc. is set.
To store in memory the sensitivity adjustment report or calibration test report, "Data memory ()" inthe function table must be changed.

Cautions on the use of external weights
The accuracy of the weight used for sensitivity adjustment determines the accuracy of the balance after
sensitivity adjustment.
Refer to the table on the next page to select the weight to be used for the sensitivity adjustment/calibration
test using an external weight.

7-1. Automatic sensitivity adjustment (GX-L series only)This function automatically adjusts the sensitivity of the balance according to ambient temperature change, settime or interval time using the internal weight. It works even when the display is off. After sensitivity adjustment,
the balance will output the “sensitivity adjustment report” if GLP output is set in the function table.
For the automatic sensitivity adjustment mode, “Temperature change (“Interval time ()” can be set in “Sensitivity adjustment mode (For the set time,

are available in the function table.

The Interval time can be set in the range of 0.5 hours to 24 hours in "Interval time ()" of the function

table.

CautionIf something is on the weighing pan, the balance itself will judge that it is in use and will not perform
automatic sensitivity adjustment. The criteria for performing automatic sensitivity adjustment are as follows.

0.1 g model

1 g model

200 g or more

2 kg or more

To maintain the correct sensitivity adjustment of the balance, do not place anything on the weighing pan
while not in use.
The automatic sensitivity adjustment notice (the indicator

blinking)

indicates that the automatic sensitivity adjustment will start. If the balance is
not in use, after blinking for a while, the balance will start automatic sensitivity
adjustment using the internal weight. (The blinking duration depends on theenvironment.)
Indicates that the balance is measuring sensitivity adjustment data.
Do not allow vibration or drafts to affect the balance while this indicator isdisplayed. After calibration, the balance returns to indicate the previous
display.
If the balance is determined to be tilted, automatic sensitivity adjustment will not be performed. Check the
bubble spirit level to see if the bubble is in the center circle.
However, by setting "(Level detection)" to "(Off)" in "(Environment/Display)" of thefunction table ("9. Function Table"), automatic sensitivity adjustment will be performed even if the balanceis tilted.

Tips
Although it is possible to continue using the balance even while the automatic sensitivity adjustment notice(theindicator) is blinking, use after sensitivity adjustment is completed is advisable in order to maintainthe weighing accuracy.
"Prohibit automatic sensitivity adjustment" or "Allow automatic sensitivity adjustment" can be selected in
the setting described in “8. Function Selection Switch and Initialization”.

7-5-1. Correcting the internal weight value AUTO (GX-L series only)This is a method to correct the internal weight value based on an external weight.
First, perform the sensitivity adjustment by referring to “7-3. Sensitivity adjustment using an external weight”.
After the sensitivity adjustment with the external weight, the balance automatically loads and unloads theinternal weight and corrects the internal weight value.
Refer to "7. Sensitivity Adjustment / Calibration Test" for usable weights.
The corrected value is stored in nonvolatile memory even if the AC adapter is removed.

Setting procedure
Correction of the internal weight value cannot be performed atfactory settings.
Refer to the setting procedure step 1 in “7-5. Correcting the internal
weight value (GX-L series only)” and enable changes to thePress and holdfor 2 seconds

Example: GX-32001L

Setting Example
When correcting the built-in weight value of the GX-32001L, if the value
becomes 19999.4 g with a 20 kg load after sensitivity adjustment using
the built-in weight, the method is to correct it to 20000.0 g with a 20 kg
load. (+0.6 g / 20 kg correction will be made.)

Setting procedure
Correction of the internal weight value cannot be performed at factory
settings. Refer to the setting procedure step 1 in “7-5. Correcting theinternal weight value (GX-L series only)” and enable changes to thefunction table and correction of the internal weight value.
1. Perform sensitivity adjustment of the balance. Then, place an

that the value displayed is within ±2 d of the correction reference
value for 20 kilograms.) If the value is not within ±2 d of the correction
value, repeat the above procedure to correct it.

Note
For example, to correct a 30 kg load by +0.6 g on the GX-32001L, input the correction value of +0.4 g

8-1. Function selection switch
The balance stores data that must not be changed unintentionally (such as adjustment data for accurate
weighing, data for adapting to the usage environment, data to control the communications interface, etc.). In
order to protect such data, "Function selection switch" is provided and either "prohibit changes " or "allowchanges/use" can be selected. When "prohibit changes" is set, inadvertent data change can be prevented
because the function cannot be activated.
There are five types of "Function selection switch":Function table

9-3. “Environment/Display” explanation
Condition ()
Sensitive response to fluctuation of a weighing value:
For powder or liquid target weighing, weighing a very light sample, or when work
efficiency is required rather than display stability, set the parameter to be a smallvalue. When set,

FAST

is displayed.

Slow response to fluctuation of a weighing value:
To prevent the weighing value from drifting due to vibration or drafts, set theparameter to be a high value. When set,

Stability band width (SLOW

is displayed.

)This item is to control the width to regard a weighing value as a stable value. When the fluctuation range of
the weighing value within a certain period of time is less than the parameter, the balance displays thestabilization indicator and the data can be output (or stored) as set in the “9. Function Table” (output),(Data(Data memory), etc.). This setting influences "auto print mode".

“d” represents scale division.
Example: For the GX-62001L, if 1 g display is selected with the(±1 d)SAMPLE

key, 1 g is 1 d.

The stabilization indicator will not display if the value is not stable enough, and it will
disappear if there are even slight fluctuations in the weighing value. To perform
weighing with strict judgment, set the parameter to a low value.

(±3 d)The stabilization indicator becomes less responsive to slight fluctuations in theweighing value. To prevent the weighing value from drifting due to factors such as
the usage environment, set the parameter to a high value.

Hold function ()

Mode A (Average hold, animal weighing)This function is used to weigh a moving object such as an animal. When the weighing data is over theweighing range from zero and the display fluctuation is within the stabilization range for a fixed period of
averaging time, the processing indicator illuminates and the balance displays the average weight of theweighing data. When the animal or sample is removed from the weighing pan, the display holds the displayed
value for five seconds, and then returns to zero*1 automatically. This function is available only when the holdfunction parameter is set to “ ” (the display hold markHOLDilluminates) and any weighing unit otherthan the counting mode is selected. The stabilization range and averaging time are set in “
and “

(Condition)”(Stability band width)” in the “9. Function Table”.

Mode B (hold when stable)
When the weighing value is beyond a certain range from zero (same weighing range as mode A) and thestabilization indicator lights up, the displayed value is held. When the object to be weighed is unloaded, thedisplay is automatically set to zero*1 after the display is maintained for 5 seconds. This function is available
when the balance is in other than counting mode.
*1

If the value is within the zero range, the zero point will be updated, and if the value is above the zerorange, tare will be subtracted.

Zero tracking ()

This function automatically tracks zero-point drift caused by changes in the environment and stabilizes thezero display. When the weighing value is only a few "d", turn the function off for accurate weighing.
“d” represents scale division.
The tracking function is not used. When the weighing value is only a few "d", turn the function off for
accurate weighing.
The tracking function is used. Normal zero tracking. (±1 d / 1 second)
The tracking function is used. Strong zero tracking. (±1 d / 0.5 seconds)
The tracking function is used. Very strong zero tracking. (±1 d / 0.2 seconds)

Display refresh rate ()

The periodic time to refresh the display. This timing also applies to data output.
This parameter influences "baud rate", "data output pause" and the operation in the stream mode.

Decimal separator ()

A symbol used as a decimal separator (point/comma) can be selected.

Auto power-ON ()

When the AC adapter is plugged in, the display is automatically turned on without pressing the

ON:OFF

key and the balance enters weighing mode. This function is used when the balance is built into an automatedsystem. Note that, for accurate weighing, the balance should be provided with power for at least half an hour
after being turned on.

Auto power-OFF ()

This is a function to automatically turn off only the display when there is no operation made for a certain
amount of time (approx. 10 minutes) while the power is on.

Readability ()

For weighing with lower precision, the readability digit can be turned off without key operation. This is usefulwhen built into an automated system.

Buzzer ()

Select ON / OFF for the built-in buzzer that sounds when a key is operated or the state changes.

75Display when power-on ()

You can choose whether the balance will automatically zero the display when the power is turned on or startfrom the previous weighing value without automatically zeroing the display when the power is turned on.
The tare value memory is useful when a hopper or other device is attached to the weighing pan and thepower must be turned off during discharge weighing. Note that this function is disabled when the holdfunction is on.

Backlight brightness ()

Select the brightness of the backlight of the LCD display.

Bubble sprit level lighting ()

Select ON / OFF for the LED that illuminates the bubble sprit level.

Impact shock detection ()

9-8. Application mode explanation
Normal weighing mode ()

This is the normal weighing mode set at the factory.

Capacity indicator mode ()

In this mode, the balance displays the relation between the load and weighing capacity in percent for normal
weighing.
(Zero: 0%. Weighing capacity: 100%.)

CautionThis mode cannot be used when the data memory function (Statistical calculation mode ().

)

In this mode, the balance performs statistical calculation of weighing values and displays/outputs the results.
For details, refer to “12. Statistical Calculation Mode”.

Flow rate measurement mode ()

In this mode, the balance calculates flow rate (change in weighing values over time).
For details, refer to “13. Flow Rate Measurement”.

ID Number and GLP Report10-1. Main objective
The data output compliant with "GLP/GMP" can be output to a personal computer or optional printer using
interfaces such as RS-232C.
The balance can output the following GLP/GMP compliant reports via RS-232C or USB.


Sensitivity adjustment report (Output for sensitivity adjustment using the internal weight [automatic
sensitivity adjustment and sensitivity adjustment])

Sensitivity adjustment report (Output for sensitivity adjustment using the external weight)

Calibration test report (Output for calibration test using the external weight)



Breaks (“Title block" and "End block") for easy management of a series of weighing data.

The GLP/GMP compliant report includes the balance manufacturer (A&D), model name, serial number, ID
number, date, time, and space for signature. For a sensitivity adjustment or calibration test, the result andthe weight used are also included.
Changing the function table enables the balance to store sensitivity adjustment report and calibration test
temporarily in data memory in order to output all at once.

Note For the setting, refer to "11. Data Memory".
The ID number can be used as an identification number for the balance during maintenance of the balance.
The ID number is stored in non-volatile memory even if the AC adapter is removed, and is valid until a newregistration is made.
For confirmation and setting of the time and date, refer to "9-4. Clock and calendar function” in “9. Function
Table”.
By setting "(GLP output)" to "(Outputs with an external clock)" in "(Data output)" of thefunction table ("9. Function Table"), it is possible to output the clock data of an external device (printer, etc.)
without outputting the built-in clock data of the balance.
When printing GLP output with an AD-8127 multi-functional compact printer connected to the balance, thetime and date can be printed using the printer's clock function. ("9. Function Table")
Centralized management with the AD-8127’s password lock function is effective in preventing falsificationof the time and date.
To output data compliant with GLP, GMP, etc., the AD-8127 printer must be set to dump printing mode.
When the external key print mode is in use for printing the weighing value, pressing and holding the ENT
key of the AD-8127 (for about 2 seconds) switches between the external key printing mode and dump
printing mode.

Statistical calculation mode statistically calculates the weight data, and displays or outputs the results. To use
this function, set "(Application mode)" to "" in "(Application function)" of the function table (“9.

Function Table”) while referring "12-1. How to use the statistical calculation: Preparation". To return to normal
weighing mode (factory settings), set "(Application mode)" to " ".

Statistical items available are number of data instances, sum, maximum, minimum, range (maximum minimum), average, standard deviation, coefficient of variation, and relative error. What statistical items to
output can be selected from the four modes of "(Statistical function mode output items)" in “(Application Function )” of the function table (“9. Function Table”).
Incorrect data input can be canceled by key operation if it is immediately after the input.
Turning the balance off will delete the statistical data.
The standard deviation, coefficient of variation, and relative error are obtained by the equation below:
Standard deviation＝�

The GX-L/GF-L series has a flow rate measurement mode to calculate the change in weighing values withtime.
The balance calculates the flow rate from the weight change over time and indicates the flow rate value perunit time on its display.
The flow rate can be calculated for both filling and discharging.
The volume (mL) flow rate can be also calculated by setting the density of a measurement sample.

The display switches between the weight value and the flow rate value by key operation, so the total value
can be confirmed during filling or after filling.

By connecting the balance to a PC and using the WinCT-FRD software for Windows, the weight and flowrate values changing with time can be graphed in real-time and recorded on the PC.
The WinCT-FRD software can be downloaded from our website: http://www.aandd.jp/

132Weighing and flow rate data can be simultaneously output to an external device.
It makes designing a device such as PLC easier when building dispensing systems and so on. In addition,
it is possible to transmit a contact signal when a weight reaches a specified value by using the optional
comparator output (GXL-04).

The flow rate is calculated by the following formula.

WeightFlow rate

Ct: Flow rate calculation timeW

W: Current weight
W’: Weight before flow rate

Change in weightcalculation time

= W - W’

Ct
Time

The FRD function stores the weighing data in the balance and calculates the flow rate.
By turning off the power or pressing theZEROkey, the stored weighing data is initialized. Afterinitializing the weighing data or switching to the flow rate measurement mode from the other mode, the flowrate value is displayed as " " during the preset flow rate calculation time.
A stable flow rate value cannot be calculated until the preset flow rate calculation time has elapsed sinceweighing started.
The flow rate can be calculated in either for increasing weight (filling) or decreasing weight (discharging).
Even in the case of decreasing weight, the flow rate is calculated as a positive value.

Note Variation in the calculated flow rate may change depending on the flow rate calculation time setting.
Refer to "13-1-1. Examples of manual setting of flow rate calculation time (Ct)”.

Minimum Weight Alert Function

Minimum weight is the minimum sample weight required to perform correct quantitative analysis taking themeasurement error of the balance used into account. If the sample amount is too small, the proportion of
measurement error in the measured value increases, and the reliability of the analysis result thus may drop.
The minimum weight alert function makes it possible to judge immediately whether the sample amount meetsthe set minimum weight. This function can be used only with "g" mode. With this function, "" displays at

the top of the unit.
"" is displayed blinking when the sample amount is less than the set minimum weight. When the sample

amount exceeds the set minimum weight, "" is hidden.

The minimum weight can be changed in the function table.
Note that when the set value is 0 g, the alert is not displayed even if the minimum weight alert function isenabled (or). Also, the minimum weight cannot be set above the weighing capacity.

There are two types of alert displays:"Excluding near zero""Including near zero"
Near zero is within 0 g ±10 d.

CautionThis function cannot be used together with the statistical calculation function and the data memory function.

Repeatability Check Function (GX-L series only)

Repeatability is an index of variation in measured values when the same weight is repeatedly loaded andunloaded, and is usually expressed as the standard deviation (σn-1). The GX-L series has an internal weight.
With the repeatability check function, the balance obtains 10 measurement results using the internal weightand displays its standard deviation. It is possible to use this function with the installed balance in order to checkthe repeatability in the installation environment.
Example: "Standard deviation = 0.1 g" shows that the results of repeated measurements of the same sample
fall within the range of ±0.1 g with a frequency of about 68%.

2) Precautions when connecting multiple peripheral devices at the same time.
Peripheral devices such as the remote display, remote controller, and extension controller for weighing lines
shown in the table display the weighing value in real time. So, the balance is normally operated in acontinuous output mode (stream mode).
On the other hand, if the balance is set to stream mode, it may be difficult to use when connecting aperipheral device such as a printer, PLC, and PC. In order to connect peripheral devices operated in stream
mode and another at the same time, "" in the function table enables RS-232C to operate irregularly

according to the connected peripheral device.

18519-5. Connecting to a PC
19-5-1. Quick USB mode
Quick USB mode is a function used to connect the balance with a PC using a USB cable to directly input theoutput data of the balance into PC software such as Excel or Word. Windows XP or later is supported.
Since the balance uses a standard Windows driver (HID), no installation of a special driver is necessary andcommunication is possible just by connecting the balance to the PC.

Caution
Quick USB is a one-way communication from the balance to the PC. It is not possible to send control
commands from the PC to the balance.
Turn off the PC’s screen saver and stand-by modes.
Do not use quick USB when the output mode of the balance is set to stream mode.
As stream mode continuously outputs weighing data to the PC from the balance, irregular operation may
occur on the PC.
Refer to "20. Checking the software version of the balance" for how to confirm the software version of thebalance.

186

19-5-2. Virtual COM mode
Virtual COM mode is a function used to connect the balance with the supplied USB cable and create a COM
port on the PC side for bi-directional communication.
Windows 7 or later is supported. Except for Windows 10, Windows 11, when using for the first time, you needto install a special driver on the PC.
For details on how to install the driver, please refer to "How to install the Virtual COM mode driver" for the GXA / GF-A series USB interface on our website (http://www.aandd.jp)
When selecting a COM port with Win CT data communication software, the same data communication as RS232C will be available.
With Virtual COM mode, no settings for baud rate, data bits, parity and stop bits are necessary.

CautionIt may take time to install the Virtual COM mode driver for the first time.

About the function table
When using Virtual COM mode, please set the balance’s function table “” to bi-directional USB virtualCOM.

19-5-3. RS-232C
The RS-232C interface of the balance is the DCE (Data Communication Equipment) that can be connected toa PC. The RS-232C cable used for connection is the straight type. If there is no RS-232C connector on thePC, please connect in USB Virtual COM mode.

187

19-5-4.

WinCT data transmission software(USB Virtual COM mode or RS-232C)

When a PC is connected via a USB interface in virtual COM mode or with a RS-232C cable, weighing data
can be easily received by the PC with the use of the WinCT data communication software for Windows. WinCT
can be downloaded from our website (https://www.aandd.jp). Please refer to "Setup manual" and "Operation
manual" for WinCT on our website (https://www.aandd.jp) for installation and setup.
There are three applications in WinCT: RsCom, RsKey, and RsWeight.

RsComCommands can be transmitted to control the balance.
The data transmitted from the balance can be displayed and the data saved as a text file (.txt).
Multiple windows can be opened at the same time when multiple balances are connected.
Other applications can be run at the same time as RsCom. (Does not exclusively occupy the PC)
GLP output data from the balance can be received.

RsKey
The weighing data can be directly input into an application.
Any applications that have a keyboard input function are supported, such as Word and Excel.
GLP output data from the balance can be input.
Using the test display function, the PC can be used as an external display for the balance (when the balance
is in stream mode).

RsWeight
The weighing data transmitted from the balance can be displayed in graph form on the monitor in real-time.
Maximum, minimum, average, standard deviation, and coefficient of variation values can be calculated anddisplayed on the monitor.

188

19-6. Windows communication tools for parameter setting(“WinCT-ParamSet”)
WinCT-ParamSet is data communication software for Windows that enables a PC to change the function
table settings in the GX-L/GF-L series balances. RS-232C is used for communication with a PC. Prepare
an appropriate cable to connect the PC to the balance (e.g., serial / USB converter AX-USB-9P).
WinCT-ParamSet can be downloaded from the "Software" page of A&D website (https://www.aandd.jp).
To install and setup WinCT-ParamSet, download the software from "DOWNLOAD WINCT-PARAMSET" on
A&D website and refer to:“WinCT-ParamSet_Set_Up_EN_Ver.1.**.pdf” and“WinCT-ParamSet_Instruction_Manual_EN_Ver.1. **.pdf”.
(The above file names vary depending on the software version of "WinCT-ParamSet", and a number from0 to 9 is entered in place of "*".)
ID number and function table settings can be read from the balance and changed simultaneously.
Settings can be saved in CSV file format.
Settings can be written to the balance by reading a saved CSV file.

CautionExcept for the ID settings, settings that require numerical input (e.g., unit weight setting for piece counting)cannot be set with this software. Use the keys on the balance to set.
This software cannot be used when the password lock function of the balance is enabled. Also, it cannot
be used to change from disabled to enabled. Use the keys on the balance to set the password lock function.
When writing the settings from a saved CSV file, the software version of the balance described in the CSV
file must match the software version of the balance it will be written to.

189

19-7. Commands
By sending a specified command from a PC or a PLC to the balance, it can be controlled for operations suchas requesting weighing data, operating the keys, and changing the parameters. Add a terminator (<CR> <LF>
or <CR>) to the command character string when sending a command to the balance by setting ““ in thefunction table.

19-7-2. The <AK> code and error codes
When(AK, error code on) is set in the function table, the balance always responds to reception of allcommands sent from a PC or a PLC. Communication reliability is improved by checking the responding code.
When(AK, error code on) is set in the function table, the balance responds with the following.

When sending a command requesting various data to the balance, if the balance cannot transmit therequested data, it sends an error code (EC, Exx). If the balance can output the requested data, therequested data will be sent.
When sending a controlling command to the balance, if the balance cannot execute the command, it sends
an error code (EC, Exx). If the balance can execute the command, it sends the <AK> code.
<AK> code is the ASCII 06h code.
The commands below are processed by the balance, so it will send the <AK> command not only when acommand is received, but also at the end of processing. If the process does not end normally, the balance
sends an error code (EC, Exx), in which case the error is canceled with the CAL command.

19-8. The UFC function
By using the Universal Flex Coms (UFC) function, it is possible to arbitrarily output contents of your choice
when outputting the weighing data. You can also output a character string when printing a barcode with a label
printer or the like.
In order to use the UFC function, it must be set to function(UFC function on).

19-8-1. UFC program commands
To select the output format to use, send the program command from the PC and store it in the balance. The
stored output format is saved even when the balance is turned off.

How to create program commands
The maximum number of characters for a program command is 512.
First, add the PF command.
Program commands are combined in comma-delimited or space-separated form, but they can be omitted
to reduce the number of characters. However, the comma after the PF command cannot be omitted.
The maximum output characters per line by UFC is 416 characters.
In the output examples, “ ˽ ” indicates a space.

Example To output 12 spaces: $SP*12
To output 9 <CR>’s: $CR*9

When sending a program command of two or more lines, adding "& " at the end of one line the balance will
judge the next line as the continuation of the program command. (Only RS-232C)
The balance sends an error code if there is a problem after receiving a program command and sends an<AK> code if there is no problem. <AK> code is ASCII 06h code.
The UFC setting tool WinCT-UFC is available for inputting program commands. WinCT-UFC can be
downloaded from A&D website (https://www.aandd.jp).

Troubleshooting

22-1. Checking the balance performance and environment
Since the balance is a precision instrument, in some cases it may not be able to measure correct values due
to adverse effects of the measurement environment or measurement method.
If repeatability is poor when the sample is loaded and unloaded several times, or if the balance seems to be
operating abnormally, check the following items. If the problem persists after checking each item, contact yourlocal A&D dealer for repair.
"Frequently Asked Questions" and answers to them are also posted on our website (https://www.aandd.jp).

1. Checking that the balance works properly.
Check the operation of the balance using the self check function. Refer to "6-2. Self check function /automatic setting of minimum weight with ECL”.
A message will be displayed if there is a fatal failure.
As a simpler test, check the repeatability with an external weight.
Be sure to place the weight in the center of the weighing pan.
As a precise test, check the repeatability, linearity, weighing value, etc. with a weight of a known weight.

2. Check that the measurement environment and method are appropriate.
Check each item below.
Operating environment
Is the weighing table solid enough?
Is the balance level? For how to adjust the bubble spirit level, refer to "2-2. Precautions before use(Installation considerations and preparation)".
Is the operating environment free from vibration and drafts?
Is there any strong electrical or magnetic noise source such as a motor near the balance?
Weighing method
Is the weighing pan set so that it does not touch other parts such as the breeze break and dust plate frame?
(Is it installed correctly?)
Do you always press theZERO

key orTARE

key before placing your sample on the weighing pan?

Do you place your sample in the center of the weighing pan?
Did you perform a sensitivity adjustment before weighing? (GX-L only)
Did you warm up the balance before weighing by connecting it to a power supply with the AC adapter forat least half an hour?
Sample and container
Is the sample free from moisture absorption or evaporation due to the influence of ambient temperatureand humidity?
Is the temperature of the container of the sample acclimatized to the ambient temperature? Refer to "2-3.
Precautions during use (for more accurate weighing)".
Is the sample free of static electricity? Refer to "2-3. Precautions during use (for more accurate weighing)".
Is the sample a magnetic material (iron, etc.)? Care must be taken when weighing magnetic materials.
Refer to "2-3. Precautions during use (for more accurate weighing)".
