The functions and operating procedures of the balance are explained in detail in other documents
besides this manual.
The following three manuals can be downloaded from our website https://www.aandd.jp.
1. [Communication Manual]
Using the communication function of the balance, a personal computer (PC) or printer
This is a supplementary manual for connecting to peripheral devices.
2. [GX-AE Series/GX-A Series/GF-A Series Instruction Manual]
This is an instruction manual for understanding and fully utilizing the precision electronic balance
GX-AE/GX-A/GF-A series.
3. [Flow Rate Display (FRD) Function]
This is a supplementary manual for using the flow rate measurement function
(FRD: Flow rate display).
2. Installation And Precautions
The balance is a precision instrument. Unpack it carefully. Keep the packing material to be used for
transporting the balance in the future. The packing contents depend on the balance model. See the
illustrations to confirm that everything is contained.

Note
□ Please confirm that the AC adapter type is correct for your local voltage and receptacle type.
□ Please use the specified dedicated AC adapter for the balance.
□ Do not use the included AC adapter for models that are not considered compatible with the AC
adapters.
□ If you use the wrong AC adapter, the balance and other equipment may not operate properly.

2-1 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 anti-vibration 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.
□ Warm up the balance for at least 30 minutes. Plug in the AC adapter
as usual.
□ Calibrate the balance before use or after moving it to another
location. Refer to the separate instruction manual "7. Calibration".
Caution
Do not install the balance where flammable or corrosive gas is present.

Key When pressed and released When pressed and held
(for 2 seconds)
Turns the display ON:OFF . The standby indicator is displayed when the display is
turned off. The weighing mode is enabled when the display is turned on.
When password function is enable, password input display will be displayed. Refer
to the separate instruction manual "19-4 How to Input The Password At The Start Of
Weighing"
This ON:OFF key is available anytime. Pressing the ON:OFF key during
operation will interrupt operation and turn the display OFF. *
In the weighing mode, turns the digit for
readability on and off.
In the counting or percent mode, enters the
sample storing mode.
- Enters the function table mode.
Please refer to the separate
instruction manual "9. Function
Table".
- Runs the repeatability check
function when pressed and held for
another 2 seconds after the function
table menu is displayed.
Please refer to the separate
instruction manual "20.
Repeatability Check Function".
(GX-AE / GX-A series only)

4. Calibration
Since the balance's resolution is high, weighing values may change due to gravity and daily
environmental changes.
4-1 Automatic Calibration (GX-AE/GX-A Series Only)
The GX-AE/GX-A series automatically adjusts the balance sensitivity using the built-in weight
according to the temperature change of the operating environment or the set time and interval time. For
details, refer to "7-1 Auto calibration" in the separate instruction manual.
4-2 One-Touch Calibration (GX-AE/GX-A Series Only)
This function calibrates the balance using the internal mass.
1. Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on the
weighing pan.
2. Press the CAL key. The balance displays .
3. The balance performs calibration using the internal mass. Do not allow vibration or drafts to affect the
balance.
4. After the calibration, If the "GLP output ( )" parameter of the function table is set, the balance outputs a
sensitivity adjustment execution record.
5. The balance will automatically return to weighing mode after calibration.
4-3 Calibration Using An External Weight
This function calibrates the balance using an external weight.
1. Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on the
weighing pan.
2. Press and hold the CAL key for 2 seconds until is displayed, then release the key.
3. Make sure that nothing is on the weighing pan and press the PRINT key to weigh the zero point.
Do not apply vibration, etc.
4. Place the external weight on the weighing pan and press the PRINT key. Do not apply vibration
etc.
5. Remove the external weight from the weighing pan.
6. After calibration, if GLP output is set, "sensitivity adjustment execution record" is output or stored in
data memory.
7. The display automatically returns to weighing display.
8. Place the external weight again and check that the set value is ± 2 digits.
If it is out of range, pay attention to the surrounding environment and start from "1".
