The GF-A/GF-AWP series does not have an internal mass for sensitivity adjustment, so an external
weight is required separately for sensitivity adjustment.

About The GX-AE Series
In general, when the ambient humidity is less than 45%RH, nonconductors such as powders, paper,and plastics easily become charged with static electricity. The influence of static electricity may cause aweighing error of several milligrams. The ionizer neutralizes this electrical charge.
□ An ionizer (static eliminator), which causes no breeze, is built into the breeze break. The ionizer
can eliminate static electricity from the weighing sample before weighing, reducing error due tostatic electricity. (Static is eliminated by bipolar ions generated by direct-current corona discharge
being projected onto the sample.)□ The ionizer electrodes are designed to be removed for cleaning and replacement.
□ An IR (touchless) switch is attached to the ionizer, and static elimination can be started without
touching ionizer.
□ Power is supplied from the balance to allow the ionizer to be operated without using an AC adapter.
□ PRINT or RE-ZERO or the static elimination function of the ionizer can be operated by using theoptional foot switch (AX-SW137-PRINT or AX-SW137-REZERO).
□ A removable glass breeze break is equipped as standard.
□ As an option board is installed, so other options (GXA-03/04/06/09/17/23/24/25/26, FXi-08, etc.)
cannot be used.
□ For instructions on using the ionizer and IR switch, download the instruction manual for "GXA-17
Large Glass Breeze Break with Ionizer" from our website (https://www.aandd.jp) and refer to it.

13Installing The Balance
Step 1. Decide where to install the balance, taking into consideration the content of “2-2 Precautions”, below.
Step 2. Assemble the balance while referring to the explanations in the previous section.
Step 3. To level the balance, adjust the leveling feet so that the air bubble is in the red circle of the
bubble spirit level.
Step 4. Confirm that the adapter type is correct for the local voltage and power receptacle type.
Step 5. Insert the AC adapter into the AC adapter jack on the rear of the balance, and then plug theAC adapter into an outlet.

Precautions
To get the optimum performance from the balance and acquire accurate weighing data, note the following:□ Install the balance in an environment where the temperature and humidity are not excessive.
The best operating temperature is about 20°C ±2°C at about 45~60%RH relative humidity.
□ Install the balance where it is free of dust.
□ The weighing table should be solid, free from vibration and drafts, and as level as possible. (An antivibration table or stone table is ideal)□ Install the balance in a stable place avoiding vibration and shock. Corners of rooms on the first floor
are best, as they are less prone to vibration.
□ Install the balance where it is not affected by heaters or air conditioners.
□ Install the balance where it is not exposed to direct sunlight.
□ Install the balance away from equipment which produces
magnetic fields.
□ Level the balance by adjusting the leveling feet and confirm
it using the bubble spirit level.
□ Be sure to warm up the balance before use for at least 30
minutes (with the AC adapter connected to the power
supply).
□ Adjust the sensitivity of the balance before use or after
having moved it to another location. Refer to "7. Sensitivity
adjustment".

Leveling footThe GX-AWP/GF-AWP series

Bubble spirit level□ The dustproof and waterproof level of the balance is equivalent to IP65, and its second digit, “5”,corresponds to "having no harmful influence by receiving direct jet of water". Washing with strong waterpressure or submersion in water may cause water to enter the balance and cause a malfunction.
□ When installing and using the balance under conditions requiring dustproof and waterproof
performance, make sure that the AC adapter plug is fully inserted into the AC adapter jack and thatthe terminal cover is attached to the RS-232C interface or the waterproof RS-232C cable(AXKO2737-500) is used.
□ If the RS-232C terminal cover is removed or the waterproof RS-232C cable (AX-KO2737-500) is not
used, protection against dust and water is not provided.

Caution
Do not install the balance where flammable or corrosive gas is present.

During Use
For precise and accurate weighing, please take notice of the following.
□ Weighing errors may occur due to the influence of static electricity.
Note that if the ambient humidity drops below 45%RH, insulators
The Charged
such as plastics are liable to have static electricity. Ground the sample
balance and perform the following as needed.
Metal case
 Use the built-in ionizer to remove static electricity (GX-AE
series only).
 Use the GXA-25 or AD-1683A static eliminator, sold separately,
to directly remove static electricity from the sample.
 Increase the relative humidity at the place where the balance isinstalled.
 Weigh the sample in a conductive metal container or the like.
Ground Wipe off charged materials such as plastic with a damp cloth tosuppress static electricity.
□

On models that come standard with a small breeze break, the parts of the small breeze break may
be charged for some time after being unpacked or when the humidity is low. If the measured value
is not stable or repeatability is poor, remove the small breeze break and try again. Wipe thetransparent plates with a damp cloth to remove static electricity to solve the problem of them
becoming charged. It is also effective to use the GXA-25 or AD-1683A static eliminator, soldseparately, or a commercially available antistatic agent.

15□ 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
weighing.
□ Weighing errors may occur if there is a difference between the
Magnetic
ambient temperature and temperature of the sample (and thematerial
container). 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
the sample and the container, try to acclimatize them to the Convection
ambient temperature.
40 C□ Perform the weighing operation carefully and quickly. If
20 C
measurement takes a long time, error-inducing factors will
increase due to changes in temperature and humidity in theweighing chamber, air turbulence or reaction/humidity absorption
by the sample.
□ Do not leave the sample on the weighing pan for an extended
period of time. If a sample is left on the weighing pan for a longtime, the measured value will change due to deviation from thezero point caused by environmental changes or due to creep
phenomenon.
□ 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.
□ 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 the RE-ZERO key before weighing in order toeliminate 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.
□ It is advisable to use the standard accessory display protection
cover in order to prevent foreign substances such as powder,liquid and metal pieces from entering the balance.

GX-AWP/GF-AWP series□ The balance is dustproof and waterproof, and the case is highly airtight. Therefore, for example,
minute pressure fluctuations in the chamber caused by opening and closing the door may cause
instability of the display. Before weighing, allow the pressure fluctuations to settle.
□ If water droplets or powder remains on the waterproof diaphragm and the pan support boss, theperformance of the balance may be impaired. Please clean the balance before using it.
□ If the waterproof diaphragm is deformed due to overload, etc., the weighing value may become
unstable until the deformation subsides.

16Precautions After Use
□
□
□
□
□

Avoid mechanical shock to the balance.
Do not disassemble the balance. Contact the local A&D dealer if the balance needs service orrepair.
Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that ismoistened with warm water and a mild detergent.
Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid
spills and excessive dust.
The GX-AWP/GF-AWP series is dustproof and waterproof, but it cannot withstand water pressure
due to submersion and the like.

Power Supply□

When the AC adapter is connected, the balance is in the standby mode if the standby indicator ison. This is a normal state and does not harm the balance. For accurate weighing, keep the AC
adapter connected to the balance and AC power unless the balance is not to be used for a long
period of time. Please warm up the balance for at least 30 minutes (one hour for 0.0001g models).

Based on the unit mass of the reference sample (weightof one piece), the balance calculates and displays how many pieces are weighed. The smaller thevariation in the unit mass, the more accurate the count (the number of pieces). In addition, the ACAI
function described later can be used to further improve the counting accuracy while weighing.
Note* It is recommended that the unit mass (weight of one piece) of the sample to be weighed should
be at least 10 times the readability (g) of the balance.
* If there is a large variation in the sample unit mass values, it may not be possible to countaccurately.
* If counting error is large, frequent use of the ACAI function is advisable. As one of the othermethods, try dividing the measurement into multiple times.

Selecting the counting mode
1. Press the

MODE

key to selectPC5( PC5 = unit)

Storing a sample unit mass
2. Press the SAMPLE key to enter the sample unit mass storing
mode. Note that even in the storing mode, pressing the MODE.
key switches to the next mode.
3. To select the number of samples, press the SAMPLE key
several times. (1025501005 pieces)
Note
Since the sample unit mass is usually considered to have somevariation, the larger the number of samples for registration, themore accurate the count can be.
4. Place a container on the weighing pan, if necessary.
Press the RE-ZERO key to cancel the weight (tare). The
number specified in step 3 appears.
25.0 is displayed if 25 is selected in step 3.
5. Place the specified number of samples on the pan. In thisexample, 25 pieces.
6. Press the PRINT key to store the unit mass. The countdisplay appears. (e.g. 25 PC5 is displayed with 25 pieces.)
Note* The balance prompts to add more samples if it judges that theloaded sample is too light (resulting in large counting error).
Add the displayed number of samples and press the PRINT
key again. When the unit mass is stored correctly, the counting
display appears.
* If the balance judges that the mass of the sample is too light tobe registered as the unit mass, it displays Lo .
* Registered unit mass is stored even when the power is turned off.

Automatic Counting Accuracy Improvement (ACAI)This function automatically improves the counting accuracy as thenumber of samples increases. (Errors will be reduced as sample
weight variations are averaged.)

Processing markAfter registering the unit mass in step 6, proceed to step 8 below.
8. Add a few samples. Then the processing indicator turns on. (Three or more samples are requiredin order to prevent errors. The processing indicator does not turn on if overloaded. Add as many
samples as the displayed number.)
9. Do not touch or move the samples on the pan while the processing indicator is blinking. (Theaccuracy is being updated.)
10. The accuracy is updated after the processing indicator turns out. Each time this process is repeated,the counting accuracy will improve further. The range of ACAI after exceeding 100 is notpredetermined. Add as many samples as the displayed number.
11. Remove all the samples used with ACAI from the pan and start counting work.
Note□ Do not change units during ACAI processing.

Storing the unit mass
With the data memory function, up to 50 unit masses can be stored.
1. Set the function setting item "Data memory ()" to "Stores
unit mass in counting mode ()".
Refer to "9. Function Table".

Impact Shock Detection Function

The GX-AE/GX-A/GF-A series has a function to detect impact shocks to the mass sensor section andto display the impact level.
By lowering the impact level at the time of loading, it is possible not only to alleviate variation in theweighing 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.

Note□

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.

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 (or2 ), the login user information is added

when outputting the impact history. (Balance software version 1.211 or later.)Note□ If data instances exceeds 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 energized (during transport, etc.) is not stored.

Output Impact History
The stored impact history can be output by sending a specified command to the balance or performing
key operation.
Note□ The impact history format differs depending on the software version of the balance.
Output by command
The stored impact data will be output all at once by sending a “ ?SA” command to the balance.

Sensitivity Adjustment / Calibration Test

Since the balance's resolution is high, weighing values may change due to gravity and daily
environmental changes. It is necessary to perform sensitivity adjustment with the weight in order to keep
the weighing values from changing even if gravity or the environment changes.
It is recommended that you perform sensitivity adjustment if the balance is installed for the first time or
relocated, or when the weighing values change significantly in daily inspection, etc.
Sensitivity adjustment means to adjust the weighing value of the balance using the reference weight orinternal mass. Calibration test is to weigh with the reference weight and compare how much the result
deviates from the reference value. (Sensitivity adjustment is not performed in calibration test.)

Sensitivity adjustment
Automatic sensitivity adjustment ····················· Automatically adjust the balance using the internalmass according to ambient temperature change, settime or interval time. (GX-AE/GX-A/GX-AWP series)
Sensitivity adjustment using the internal mass ··· Using the internal mass, adjust the balance with asingle touch. (GX-AE/GX-A/GX-AWP series)
Sensitivity adjustment using an external weight ·· Using an external mass, adjust the balance with an
external mass.

* No adjustment is made.
(GX-AE/GX-A series 0.0001g models)Caution□ Do not allow vibration or drafts to affect the balance during sensitivity adjustment.
□ To output the data for GLP/GMP using the RS-232C interface, set "GLP/GMP output ()" of"Data output ()". Refer to "9. Function Table". The time and date can be added to the GLP/GMP
report. If the time/date is not correct, you need to adjust it. Refer to "9-7 Clock and Calendar
Function". The calibration test is a function that is active only when the output of maintenancerecords compatible with GLP/GMP, etc. is set.
□ By setting "Data memory ()" of the function table, the data of sensitivity adjustment report andcalibration test report can be stored in memory.

Automatic Sensitivity Adjustment(GX-AE/GX-A/GX-AWP Series Only)
This function automatically adjusts the sensitivity of the balance according to ambient temperaturechange, set time or interval time. It works even when the display is off. If GLP output is selected in thefunction table, the balance outputs the sensitivity adjustment report after the sensitivity adjustment.
□

In the automatic sensitivity adjustment mode, the temperature change (CFnc 0), the set time (CFnc□1), or the interval time (CFnc 2) can be set with the function setting CFnc.
For the set time, three items, CtiME 1, CtiME 2 and CtME 3, can be set in the function table.

□

Interval time can be set from 0.5h to 24h with function setting C i nt.

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.
0.0001g models
0.001g models
0.01g models
0.1g models
Lower than 0.5g
Lower than 2g
Lower than 20g
Lower than 20g
To maintain the accurately adjusted state, keep the weighing pan clear while not in use.
The automatic sensitivity adjustment notice (themark blinking) indicatesthat 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 mass. (The blinking duration depends on theenvironment.)
This indicates that the balance is importing sensitivity adjustment data. Do
not allow vibration or drafts to affect the balance while this indicator isdisplayed. After sensitivity adjustment, the balance returns to the previous
display.

Note
Although it is possible to continue using the balance even while the automatic sensitivity adjustment
notice (themark) is blinking, use after sensitivity adjustment is completed is advisable in orderto maintain the weighing accuracy.
Depending on the setting of "8. Function Switch And Initialization", "Change prohibited" or"Changeable (usable)" can be selected.

Sensitivity Adjustment Using The Internal Mass
(GX-AE/GX-A/GX-AWP Series Only)
Sensitivity adjustment using the internal mass can be performed with one key press.
1. Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on theweighing pan.
2. Press the CAL key. The balance displays CAL in .
3. The balance performs sensitivity adjustment using the internal mass. Do not allow vibration ordrafts to affect the balance.
4. After sensitivity adjustment, if GLP output ()" is set, a “sensitivity adjustment report” is output
or stored to data memory.
5. The balance returns automatically to weighing mode.

About the internal mass

The value of the internal mass may change due to factors such as the operating environment andaging. Correct the internal mass value as necessary. Refer to "7-5 Correcting The Internal Mass ValueOf The GX-AE/GX-A/GX-AWP Series", "7-5-1 Correcting The Internal Mass Value Of The GX-AE/GXA/GX-AWP Series (Auto)", "7-5-2 Correcting The Internal Mass Value Of The GX-AE/GX-A/GX-AWP
Series (Manual).
Since the internal mass is about 190g, the possibility of error may increase as the weighing value
increases.
To maintain the weighing accuracy, perform the sensitivity adjustment using an external weight
periodically, as described in "7-3 Sensitivity adjustment Using An External Weight".

Correcting The Internal Mass Value Of The GX-AE/
GX-A/GX-AWP Series
Internal mass value correction can be performed with function setting.

There are two correction methods as follows.
Auto········ This is a method of correcting the internal mass weight value based on an external weight.
Manual ···· This is a method of correcting by digitally inputting a correction reference value (internal
weight conversion value).

Note□

Internal mass value correction cannot be performed by default.
Refer to "8. Function Switch And Initialization" or the following setting procedure and enable
function setting change and internal mass value correction.

Adjust the sensitivity of the balance referring to "73 Sensitivity Adjustment Using An External
Weight".
This is method of correcting the internal mass
weight value based on an external weight.
After sensitivity adjustment with the externalmass, the balance automatically loads andunloads the internal mass and corrects theinternal mass value.
The corrected mass value is stored in non-volatilememory even if the AC adapter is removed.

The balance stores data that must not be changed unintentionally (adjustment data for accurate
weighing, data for adapting to the usage environment, data to control the communications interface,etc.). "Function selection switch" is provided to protect such data and to select "Change prohibited" or"Changeable (usable)". When "Change prohibited" is set, the function mode cannot be entered, so
inadvertent change can be prevented.
There are five types of "Function selection switch":"Function table", "Sensitivity adjustment using the internal mass", "Sensitivity adjustment using

Condition (Cond)
This parameter is for sensitive response to the fluctuation of a mass value. Used for
powder or liquid target mass, weighing a very light sample, or when quick response
weighing is required. After setting to this, the balance displays FAST .
This parameter is for stable weighing with slow response. Used to prevent a mass value
from drifting due to vibration or drafts. After setting to this, the balance displays
SLOW .

Stability band width (5t-b)
This item controls the width to regard a mass value as a stable value. When the fluctuation per second
is less than the parameter, the balance displays the stabilization indicator and outputs or stores thedata by function setting ( dout, dAtA, etc.). The parameter influences the "Auto print mode". Also, thereadability being displayed is 1 digit.
(E.g.) If 0.01 g display is selected by pressing the SAMPLE key on the GX-303A, 0.01 g is 1 digit.
This parameter is used for sensitive response of the stabilization indicator. Used forexact weighing.
This parameter ignores slight fluctuations of a mass value. Used to prevent a mass
value from drifting due to vibration or drafts

Hold function (HoLd) (Animal weighing mode)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 theanimal. When the animal or sample is removed from the weighing pan, the display returns to zeroautomatically. This function is available only when the hold function parameter is set to " 1 " (the animalmode indicator HOLD illuminates) and any weighing unit other than the counting mode is selected.
The stabilization range and averaging time are set in "Condition (Cond)" and "Stability band width (5tb)".

Zero tracking (trc)This function tracks zero point drift caused by changes in the environment and stabilizes the zero
point. The degree of tracking can be selected from 3 levels. If zero is not stable, increase the setting
value. When the weighing data is only a few digits, turn the function off for accurate weighing.
The tracking function is not used. Used for weighing a very light sample.

Display refresh rate (5Pd)
The periodic time to refresh the display. This parameter influences "Baud rate", "Data output pause" andthe data output rate of "Stream mode".

Decimal point (Pnt)
The decimal point format can be selected.

Auto display-ON (P-on)
When the AC adapter is plugged in, the display is automatically turned on without the ON:OFF key
operation and the balance enters weighing mode. Used when the balance is built into an automatedsystem. Half an hour warm up (more than one hour for 0.0001g models) is necessary for accurate
weighing.

Auto power-OFF (P-oFF)

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

Readability (rnG)

When weighing with rough precision, the readability can be turned off without key operation.
This is useful when built into an automated system.

Buzzer (bEEP)

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

Tare value record (P-ZEro)

After turning on the power supply, the display will not be automatically set to zero, and it will startfrom the previous weighing value. This is useful when a hopper, etc. is attached to the weighing
pan and the power needs to be turned off while weighing discharge.

Backlight brightness (di5P-LEd)

Select the brightness of the backlight of the LCD display.

Bubble sprit level lightning (LV-LEd)

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

Impact shock detection ( I 5d)

10. ID Number And GLP Report
Main Objective□

The data output compliant with "GLP/GMP" can be output to a personal computer or optional printer using
the RS-232C serial interface.

□

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 and the weight used are also included.

□

The balance can output the following GLP/GMP compliant reports via the RS-232C or USB.
 Sensitivity adjustment report(Output for sensitivity adjustment using the internal weight, automatic sensitivity adjustment,sensitivity adjustment using the external weight)
 Calibration test report(Output for calibration test using the internal weight or external weight)
 Breaks (“title block" and "end block") for easy management of a series of weighing data□

Changing the function table enables the balance to store sensitivity adjustment report andcalibration test temporarily in data memory in order to output all at once. For the setting, refer to"11. Data Memory".

□

The ID number can be used as an identification number for the balance during maintenance of thebalance.

□

The ID number is stored in non-volatile memory even if the AC adapter is removed, and is valid
until a new registration is made.

□For confirmation and setting of the time and date, refer to "9-7 Clock And Calendar Function".

□

When printing GLP output with an AD-8127 multi-printer connected to the balance, the clockfunction of the printer can be used to print the time and date. (Function table " inFo 2 ")(Balance software version 1.211 or later)
Centralized management using the password lock function on the AD-8127 side is effective inpreventing time and date tampering.
Note
To output GLP/GMP compliant reports, set the print mode of the AD-8127 to the dump print
mode. If the external key print mode is set for weighing value printing, press and hold the

ENT

key of the AD-8127 for 2 seconds to switch between the external key print mode and dump print
mode.

Output the clock data of the external device (info 2).
When outputting data such as that for GLP/GMP, setting the function table "info 2" enables use of theclock data of the external device such as a PC or printer instead of the clock data built into the balance.
Use this function to unify clock data with the clock function of an external device.

Note

□

The function to output the clock data of external devices can be used with devices that have a clockfunction and can output the date and time in response to <ESC>D and <ESC>T. (e.g. AD-8127 multi
printer, RsCom [WinCT])
For sensitivity adjustment history storage of the data memory function, the clock data built into thebalance is saved even when "info 2" is set.

The statistical calculation mode statistically calculates the weight data, and displays or outputs theresults. To use the statistical calculation mode, set the "Application function (APF)" parameter of“Application (AP Fnc)" in the function table to " 2 ", as described below. To return to the normal weighing
mode (factory setting), set "Application mode (APF)" to "0".
Statistical items available are number of data, sum, maximum, minimum, range (maximumminimum), average, standard deviation, coefficient of variation, and relative error. What statisticalitems to output can be selected from the four modes in the function table (5tAF).
□ The wrong data input can be canceled by the key operation, if 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:
where Xi is the i-th weight data,
N is number of data.

Standard deviation=
Coefficient of variation (CV)=Standard deviation

Relative error of maximum value =Relative error of minimum value =x 100 (%)
Average

Note
□ When there is data with a readability digit off, the calculation result is displayed with thereadability digit off. (Readability digit is rounded off.)□ When the data memory function is in use, the statistical calculation function cannot be used.
□ When registering the warning function of the minimum weighing value, the statistical calculation
function cannot be used.

The balance has "flow rate mode" for calculating the amount of change in weighing values over time.
For details, please download "FRD Addendum" from the A&D website (https://www.aandd.jp) and refer
to it.
□

Densities can be registered when the unit of flow rate is set to mL/*. Up to 10 densities can be
stored. If densities are set in advance, it is possible to select one according to the sample.

□

The flow rate value is calculated by the following formula.

Q=

W −W ′Ct

Q : Flow rate

Ct : Flow rate calculation time

W : Current weighing value

W’ : Weighing value before Ct

WeightWeighing value

The minimum weighing value is the minimum sample weight required to perform correct quantitative
analysis taking the measurement error of the balance used into account. If the sample amount is too
small, the proportion of the measurement error in the measured value increases, and the reliability of
the analysis result thus may drop.
With the minimum weighing warning function, it is possible to judge immediately whether the sample
amount meets the set minimum weighing value.
This function can be used only with "g" mode.
With this function, "M I N" displays blinking at the top of the unit when the sample amount is less than theset minimum weighing value. When the sample amount exceeds the set minimum weighing value,"M I N" is hidden.
The minimum weighing value can be changed with the function table. The factory setting is 0 g.
Note that when the set value is 0 g, the warning is not displayed even if the minimum weighing warning
function is enabled (MW-CP 1 or 2). Also, the minimum weighing value cannot be set above the weighing
capacity.
There are two types of warning displays:"Excluding near zero"

MW-CP Ex0

"Including near zero"

MW-CP IN0

Near zero is within 0 g ±10 digits.
Note□ When “MW-CP“ is set to a parameter other than 0, the MODE key is assigned to the minimum
weighing value setting. Therefore, the unit cannot be changed with the MODE key. (The unit isfixed to the one used immediately before.)□ To change the unit, disable the minimum weighing warning function.

The built-in underhook is used for underhook weighing such as measurement of magnetic materials or
density measurement.
To use the underhook, open the cap on the bottom of the balance as shown below.

Caution□□

Do not apply excessive force to the underhook part.
Do not open the cap unless necessary. (For protection from dust)□

The underhook can be used only in the hanging direction (pulling direction).

Cap
Underhook(Hole diameter: approx.4mm)
Bottom of the balance□

If the balance is tilted greatly, attached parts such as the weighing pan will come off. Please remove
them before work.

□

Keep in mind that draft enters the balance easily when the underhook cap is removed, affecting
the weighing values.

12317. Programmable Unit
This is a programmable unit conversion function. It multiplies the weighing data in grams by an arbitrary
coefficient set in the function table and displays the result.
The coefficient must be within the range between the minimum and maximum shown below. The settingof coefficient differs according to the balance software version. If the coefficient set is beyond the range,
an error is displayed and the balance returns to the coefficient setting mode, prompting to enter anappropriate value. A coefficient of 1 was set at the factory.

The balance is equipped with a density mode. It calculates the density of a solid according to thesample weight in air and sample weight in liquid.
For density measurement, the optional GXA-13 Density Determination Kit is recommended.
Note□

The density mode is disabled by default. To use the density mode, the function table needs to bechanged in order to enable the density mode " D5". Please refer to "Storing Units" in "4-1 Units".
Readability is fixed in density mode.

Repeatability is an index of variation in measured values when the same mass is repeatedly loaded andunloaded, and is usually expressed as the standard deviation. (σn-1).
The GX-AE/GX-A/GX-AWP series have an internal mass.
With the repeatability check function, the balance obtains 10 measurement results using the internalmass and displays its standard deviation. It is possible to use this function with the installed balance inorder to check the repeatability in the installation environment.
This function is available with balance software version 1.211 or later.
Example) "Standard deviation = 10.0 mg" shows that the results of repeated measurements of thesame sample fall within the range of ±10.0 mg with a frequency of about 68%.

Treatment Of The Balance□ Clean the balance with a lint free cloth that is moistened with warm water and a mild detergent.
□ Do not use organic solvents or chemical cleaning cloths to clean the balance.
□ Do not disassemble the balance.
□ When transporting the balance, use the packing material and box that the balance was containedat the time of purchase. For transportation, remove the weighing pan and plate holder from thebalance main body.

GX-AWP/GF-AWP specifications□

The GX-AWP/GF-AWP series dustproof and waterproof performance means it is waterproof in
everyday situations, so the weighing pan can be washed with water while still installed.
Note that if the balance is submerged in water or if water pressure is applied to the bottom of thebalance main body, water may get inside.

□

When washing the balance with water, attach the terminal cover to the RS-232C interface orconnect the waterproof RS-232C cable (AXKO2737-500).
Close the lid of the AC adapter input jack.
Make sure that the cover of the underhook is also closed.

AC adapter input jack
Close the lid when the AC adapter is not connected.

Attach the terminal cover supplied with the RS-232C interface
or connect the waterproof RS-232C cable (AX-KO2737-500).

□

If something such as water remains in the waterproof diaphragm, the weighing value may become
unstable. Be careful not to deform the diaphragm when cleaning it.

23. Troubleshooting
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 your local A&D dealer for repair.
"Frequently Asked Questions" is also posted on our website (https://www.aandd.jp).

1. Check 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 Weighing Value By 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 thecenter 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.

Other Display

AdviceThis is the automatic sensitivity adjustment notice (themark blinking). If
the balance is not used for several minutes with this mark blinking, thebalance automatically performs sensitivity adjustment using the internal
mass. The blinking period depends on the operating environment.
Although it is possible to continue using the balance even while this mark is blinking, use after
sensitivity adjustment is completed is advisable in order to maintain the weighing accuracy.

Asking For Repair
If the balance needs service or repair, please consult with your local A&D dealer.
The balance is a precision instrument. Use much care when handling the balance and observe thefollowing when transporting the balance.
□ Use the original packing material for transportation.
