GX-2002A / GX-3002A /About The GX-AE Series

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.

Static electricity
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 a weighing error of several milligrams. The ionizer neutralizes this electrical charge.

During Use

To acquire accurate weighing data, note the following:□ Discharge static electricity from the material to be weighed. When The Charged
samplea sample could have a static charge, the weighing data is
influenced. If the ambient humidity becomes 45% or less,
Metal caseinsulators such as plastics are liable to become static electricity.
Ground the balance and try the following.
An anti-static treatment has been applied to the breeze breakcomponents.
Eliminate the static electricity by GXA-25, AD-1683 as an accessory.
Or try to keep highly the ambient humidity
GroundOr use a metal shield case.
Or wipe a charged plastic sample with the wet cloth.
□ The breeze break (0.001g models only) and the clear main unit
cover are provided as accessories. The breeze breakcomponents may be charged with static electricity when they areunpacked or when the humidity is low. If the weighing value isunstable or the balance has a problem with repeatability, remove
the breeze break. Or wipe the clear plates with a moistened cloth,use an accessory DC static eliminator, GXA-25, AD-1683 or apply an
anti-static spray.
□ This balance uses a strong magnet as part of the balance
assembly, so please use caution when weighing magnetic
materials such as iron. If there is a problem, use the underhook
14

Magnetic
material

on the bottom of the balance to suspend the material away fromthe influence of the magnet.
□ Cancel the temperature difference between a sample and theenvironment. When a sample is warmer (cooler) than theambient temperature, the sample will be lighter (heavier) than
the true weight. This error is due to a rising (falling) draft aroundthe sample.

Convection
40 C
20 C

□ Make each weighing gently and quickly to avoid errors due tochanges in the environmental conditions.
□ When placing a sample on a weighing pan, do not give a strong
shock or do not exceed the weighing capacity. And place in thecenter.
□ Do not drop things upon the weighing pan, or place a sample on
the pan that is beyond the balance weighing capacity. Place asample in the center of the weighing pan.
□ Do not use a sharp instrument such as a pencil to press the keys.
Use your finger only.
□ Press the RE-ZERO key before each weighing to prevent
possible errors.
□ Take into consideration the affect of air buoyancy on a sample
when more accuracy is required.
□ Keep the balance interior free of dust and foreign materials.

□

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.

2-5□

After Use

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).

Counting Mode（PCS）

This is the mode to determine the number of objects in a sample based on the standard sample unitmass. Unit mass means the mass of one sample. The smaller the variables in each sample unit massis, the more accurate the counting will be. This series balance is equipped with the AutomaticCounting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Note* For counting, use samples that have a unit mass at least ten times greater than that of thereadability in grams.
* If the sample unit mass variable is too large, it may cause a counting error.
* To improve the counting performance, use the ACAI function frequently or divide the samples into
several groups and count each group.

Selecting the counting mode

The ACAI is a function that improves the accuracy of the unit mass automatically by increasing thenumber of samples as the counting process.
ACAI: Automatic Counting Accuracy Improvement
Processing markAfter registering unit mass of "6", proceed to the following "8".
8. If a few more samples are added, the processing indicator turns on. To
prevent an error, add three or more. The processing indicator does notturn on if overloaded. Try to add the same number of samples as
displayed.
9. The balance re-calculates the unit mass while the processing indicator is blinking. Do not touchthe balance or samples on the pan until the processing indicator turns off.
10. Counting accuracy is improved when the processing indicator turns off.
Each time the above operation is performed, a more accurate unit mass will be obtained. Thereis no definite upper limit of ACAI range for the number of samples exceeding 100. Try to add thesame number of samples as displayed.
11. Remove all the samples used in ACAI and proceed with the counting operation using theimproved unit mass.
Note

ACAI will not function on the unit mass entered using the keys, or digital input mode.

Animal Weighing Mode（Hold Function）

This is the mode to weigh a moving object such as an animal, even when the display of the weighing
data fluctuates. The hold function allows the average weight of the animal to be displayed. To use
the hold function, set the function in the function table. Refer to "9. Function Table" and "9-3
Description Of The Class Environment Display" for details.

5. Impact Detection Function
The GX-AE/GX-A/GF-A series has a function to detect impact 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 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.
Impact level display is from level 0 to level 4, 5 level.

Even if the impact detection function is turned off, it records in the balance when there is a shock.
Note□

Impact on the weighing sensor may be applied to the weighing pan at time of loading, or it may be
applied from the table on which the balance is installed.
The impact detection function also works for impact applied from the table.

Recording Impact History

Impacts of impact level 3 or higher are stored on the balance with data and time included (maximum
50 data instances).
When the password lock function is on (or2 ), the login user information is added when

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

Calibration (Sensitivity adjustment)
Auto calibration ········································· Automatically adjust the balance using the internalmass depending on the temperature change of theoperating environment or the set time and interval
time.（GX-AE / GX-A series）
Calibration using the internal mass················ Using the internal mass, adjust the balance with asingle touch.（GX-AE / GX-A series）
Calibration using an external weight ·············· Using an external mass, adjust the balance with an
external mass.

Calibration test（Sensitivity calibration）
Calibration test with an external weight············Output the result of checking the accuracy ofweighing using your own weight.
* No adjustment is made.
Calibration test with an internal mass ············· Output the result of checking the accuracy ofweighing using the internal mass.
* No adjustment is made.
（GX-AE / GX-A series with 0.0001g type）

Caution□ Do not allow vibration or drafts to affect the balance during calibration.
□ To output the data for GLP/GMP using the RS-232C interface, set "GLP/GMP output (inFo)" of"Data output (dout)". Refer to "9. Function Table". The time and date can be added to the
GLP/GMP report. If the time or date is not correct, adjust them. Refer to "9-7 Clock and Calendar
Function".
□ By setting "Data memory (dAtA)" of the function table, the data of calibration (sensitivity adjustment
execution record) and calibration test (sensitivity calibration) can be stored in memory.

Caution when using your external weight□ The accuracy of the weight used in calibration affects the accuracy of the balance after calibration.
□ Select the mass to be used for calibration and calibration tests from the table below.

Caution
If something is on the weighing pan, the balance judges that it is in use and does not perform automatic
self calibration.
The criteria that the balance judges in use 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 accurate calibrated state, keep the weighing pan clear while not in use.
This mark blinking () indicates that the automatic self calibration will
start. If the balance is not in use, after blinking for a while, the balance will
start automatic self calibration using the internal mass. The blinking duration
depends on the environment.
This indicates that the balance is importing calibration data. Do not allow
vibration or drafts to affect the balance while this indicator is displayed. Aftercalibration, the balance returns to indicate the previous display.
Note The balance can be used while the indicator blinks. But, it is recommended that tomaintain the accuracy, stop using the balance and confirm that there is nothing on the pan
and allow the balance to perform self calibration.
Depending on the setting of "8. Function Switch And Initialization", "Change prohibited" or"Changeable (usable)" can be selected.

Description Of The Class Environment Display

Condition (Cond)
This parameter is for sensitive response to the fluctuation of a mass value. Used for
powder target mass, weighing a very light sample or when quick response weighing
is required. After setting, 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, 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 persecond is less than the parameter, the balance displays the stabilization indicator and outputs orstores the data by function setting ( dout, dAtA, etc.）The parameter influences the "Auto print mode".
Also, the readability being displayed is 1 digit.
Ex. 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(5t-b)".

Zero tracking (trc)This function tracks zero point drift caused by changes in the environment and stabilizes the zero
point. When the weighing data is only a few digits, turn the function off for accurate weighing.
trc 0 The tracking function is not used. Used for weighing a very light sample.
trc 1 The normal tracking function is used.(±1 digit / 1 second)trc 2 The strong tracking function is used. (±1 digit / 0.5 second)trc 3 The very strong tracking function is used. (±2 digit / 0.2 second)59

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, to display the 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 turn off only the display automatically 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)
Select ON / OFF for the function to display impact level.
* Applicable from balance software version 1.300 or later.
Even if the function to display impact level is turned off, it is recorded inside the balance when
there is an impact.

10.ID Number And GLP Report10-1 Main Objective□

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

□

The GLP / GMP compliant report includes the balance manufacturer, model, serial number, ID
number, date, time and space for signature. It includes the results and using mass for calibrationor calibration test data.

□

The balance can output the following GLP/GMP compliant reports from RS-232C or USB.

・"Calibration report" of the calibration, using the internal mass (Calibration due to changes in auto andone-touch calibration.)・"Calibration report" of the calibration, using an external weight.
・"Calibration test report" of the calibration test, using an external weight.
・"Title block" and "End block" for the weighing data.
□

Calibration report and calibration test data can be stored in memory to output several reports atthe same time. Refer to "11. Data Memory" for details.

□

The ID number is used to identify the balance when the balance is used for maintenance management.

□

The ID number is maintained in non-volatile memory even if the AC adapter is removed.

□

For details on confirming and setting the time and date, Refer to "9-7 Clock And Calendar Function".

□

When printing the GLP output by connecting a multi-printer AD-8127 to the balance, the clockfunction of the printer can be used to print the time and date. (Function setting " inFo 2 ") (Balance
software version 1.211 or later)This is enabled when centrally managing prevention of tampering of time and date with the
password lock function on the AD-8127 side.
Note
When outputting GLP / GMP compliant reports, the print mode of AD-8127 is set to dump print
mode. If the weighing value was printed in the external key printing mode, press and hold the
ENT

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

11.Data Memory
Data memory is a function to store weighing data and calibration data in memory. The data stored inmemory are available for outputting at one time to a printer or personal computer.
The following six types of data can be stored.
Unit mass (Counting mode)

Up to 50 sets

Weighing value

Up to 200 sets

Calibration report
Internal calibration
External calibration
Calibration test report
Internal test calibration (0.0001g models only)
External test calibration

Last 50 sets

11-1 Data Memory For Weighing Data
Features□□□□□

It is not necessary to connect the printer or personal computer to the balance continually, because
the balance stores the weighing data in memory.
By storing the weighing value in the balance, weighing operation can be performed without occupying
the printer or PC for a long time.
The data in memory can be displayed on the balance for confirmation.
Data (ID number, data number, time and date) to be added to the output data can be selected in
the function setting.
The balance can store 200 sets of weighing data in memory (if time and date are added, thebalance can store 100 sets).
* For the unit mass storage method, refer to "4-3 Counting Mode (PCS)".

Storing the weighing data
Note
1. Set the "Data memory (dAtA)" parameter to "dAtA 2". Refer to "9. Function Table".
2. Specify by the "Time/Date output (5-td)" parameter whether time and date is to be added or not.
3. The storing mode depends on the "Data output mode (Prt)" parameter setting.
When set to Prt 3 (stream mode), data may not be stored correctly.
* It is also possible to change the time / date setting after storing the weighing value.

12.Statistical Calculation Mode
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 (maximum-minimum),average, standard deviation and coefficient of variation. What statistical items to output can beselected 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 and coefficient of variation 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

15. Minimum Weighing Warning Function
The minimum weighing value is the minimum necessary amount of sample to be used for correctly
performing quantitatively performing quantitative analysis, taking into consideration measurement errorof the balance.
If the amount of sample is too small, the proportion of the measurement error in the measured value
increases accordingly, and the reliability of the analysis result may drop.
By using the minimum weighing warning function, it is possible to judge at a glance whether the amountof sample meets the set minimum weight value. This function can be used only in "g" mode.
" M I N " is displayed at the top of the unit part when in use when the amount of sample is less than theset minimum weighing value, the " M I N " indication flashes.
When the amount of sample reaches the minimum weighing value or more, the " M I N " indicator willturn off.
The minimum weighing value can be changed from the function setting. The factory setting is 0 g.
If the set value is 0 g, no warning will be displayed even if the minimum weighing warning function is
ON (MW-CP 1 or 2). Also, a value greater than weighing capacity cannot be set as minimum weighing
value.
There are two kinds of warning display as follows
1"Excluding near zero"

MW-CP Ex0

"Including near zero"

MW-CP IN0

2

Near zero is within ± 10 digits of 0 g.
Note
□ If MW-CP is set to anything other than U, the MODE key will be applied to set the minimum

18.Density (Specific Gravity) Measurement
The balance is equipped with a density mode. It calculates the density of a solid using the mass valueof a sample in air and the mass value in liquid.
For measurement, it use of the option GXA-13 specific gravity measurement kit is recommended.

Note
□

□

The density mode was not selected for use when the balance was shipped from the factory. To use
the mode, change the function table and activate the density mode " D5 ". Please refer to "Storing
Units" of "4-1 Units".
Readability is fixed when in density mode.

Formula to obtain the density

 A-B
 ： Density of a sample
A: Mass value of a sample in air
V
Ｖ ： Volume of float
B: Mass value of a sample in liquid（１）Prior to measurement: Changing the function table
Prior to measurement, change the function table as follows:
1. Register the density mode.
Density mode cannot be used at the factory setting.
Please refer to "Storing Units" of "4-1 Units" and register the gravimeter mode (D5).
Density mode is selected as one of the units with the ..MODE key.
2. Select whether the object to be measured is solid or liquid. (Function setting d5 Fnc, d5)
3. In the case of solid density measurement, select a method of inputting the density of liquid.

20.Repeatability Check Function (GX-AE/GX-A Series Only）
Repeatability is an indicator of variations in measured values when the same weight is repeatedly
loaded and unloaded, and it is usually expressed in terms of standard deviation (σn-1).
The GX-AE/GX-A series have a built-in weight.
With the repeatability check function, the balance obtains 10 measurement data using the built-in
weight and displays its standard deviation.
By installing the balance and using this function, it is possible to check repeatability in the environment
where the balance is installed.
This function is available from balance software version 1.211 or later.
Ex. "Standard deviation = 10.0 mg" means that the result of repeated measurements of the same
weighing material falls within the range ±10.0 mg at a frequency of about 68%.
1. Press and hold the SAMPLE key for 4 seconds in theweighing display. After rEP tE5t is displayed, release
the key.
2. When rEP tE5t is displayed, datacollection starts automatically.
bA5FncWhile data is being collected, rEP blinks.
To cancel, press the CAL key.

22.Maintenance22-1 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 to clean the balance.
□ Do not disassemble the balance.
□ Use the original packing material for transportation.

23.Troubleshooting
23-1 Checking The Balance Performance And Environment
The balance is a precision instrument. When the operating environment or the operating method isinadequate, correct weighing can not be performed. Place a sample on the pan and remove it, and repeat
this several times. If the balance seems to have a problem with repeatability or to perform improperly, checkas described below. If improper performance persists after checking, contact the local A&D dealer for
repair.
"Frequently asked questions" and their answers are also posted on our website<https://www.aandd.jp>.

1. Checking that the balance performs properly□ Please check the operation of the balance by the self diagnosis function.
Refer to "6-2 Self Check Function / Automatic Setting Of Minimum Weighing Value By ECL".
Fatal faults are indicated by messages.
□ Check the balance performance using an external weight. Be sure to place the weight in the center of theweighing pan.
□ Check the balance repeatability, linearity and calibrated value using external weights with a known
value.

2. Checking that the operating environment or weighing method is proper
Operating environment□ Is the weighing table solid enough? (Especially 0.0001g and 0.001g model)□ Is the balance level? Refer to "2-2 Precaution" How to adjust the bubble spirit level.
□ Is the operating environment free from vibration and drafts?
□ Is there a strong electrical or magnetic noise source such as a motor near the balance?
126

Weighing method□ Does the weighing pan rim touch anything? Is the weighing pan assembly installed correctly?
□ Is the RE-ZERO key pressed before placing a sample on the weighing pan?
□ Is the sample placed in the center of the weighing pan?
□ Has the balance been calibrated using the internal mass (one-touch calibration)? (Only for
GX-AE/GX-A series)□ Has the balance been warmed up for one hour before weighing?

Sample and container□ Has the sample absorbed or lost moisture due to the ambient conditions such as temperature andhumidity?
□ Has the temperature of the container been allowed to equalize to the ambient temperature? Referto "2-3 During Use".
Is the sample charged with static electricity? Refer to "2-3 During Use".
(This occurs especially with 0.0001g and 0.001g models when the relative humidity is low.)□ Is the sample of magnetic material such as iron? There are cautions about weighing magnetic
materials. Refer to "2-3 During Use".
