Introduction

This manual describes the basic functions and operations of the balance.
For more details, refer to each manual listed in “1-1. List of Functions Explained in Separate Manuals”.

1-1 List of Functions Explained in Separate Manuals

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/GX-A/GF-A/GX-AWP/GF-AWP Series Instruction Manual] This is an instruction manual for understanding and fully utilizing the precision electronic balance GX-AE/GX-A/GF-A/GX-AWP/GF-AWP series.
  3. [Flow Rate Display (FRD) Function] This is a supplementary manual for using the flow rate measurement function (FRD: Flow rate display).

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.AND GX AE GX A GX AWP GX AWP Series Multi Function Balance

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. The 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 that 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.
  • Adjust the sensitivity of the balance before use or after moving it to another location. Refer to the separate instruction manual “7. Sensitivity Adjustment”.

About the GX-AWP/GF-AWP series

  • 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 a direct jet of water”. Washing with strong water pressure 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 that the 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.

2-2 Connecting to a PC
At the factory settings, you can transfer weighing data from the balance to a PC by following the steps below (Quick USB mode).

  1. Connect the balance and PC with the supplied USB cable.
  2. When connecting for the first time, the PC will automatically start installing the driver.
  3. Start up the PC software (Excel, etc.) for transmitting the weighing data.
  4. Set the keyboard input mode to half-width. It is not entered correctly in the full-pitch setting.
  5. Move the cursor to the place you want to input the weighing data.
  6. When you press the PRINT key on the balance, weighing data will be transmitted from the balance and input at the location of the cursor.
  7. Disconnect the USB cable when finished.
    For details, download the communication manual from the A&D website (https://www.aandd.jp/) and refer to “5. Connecting to a PC”.

Sensitivity Adjustment

Since the balance’s resolution is high, weighing values may change due to gravity and daily environmental changes.

4-1 Automatic Sensitivity Adjustment (GX-AE/GX-A/GX-AWP Series Only)

The GX-AE/GX-A/GX-AWP 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 Automatic Sensitivity Adjustment” in the separate instruction manual.

4-2 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 the weighing pan.
  2. Press the CAL key. The balance displaysAND GX AE GX A GX AWP GX AWP Series Multi Function Balance - icon5
  3. The balance performs sensitivity adjustment using the internal mass. Do not allow vibration or drafts to affect the balance.
  4. After sensitivity adjustment, if the “GLP output AND GX AE GX A GX AWP GX AWP Series Multi Function Balance - icon7parameter of the function table is set, the balanced outputs a sensitivity adjustment report.
  5. The balance will automatically return to weighing mode.

4-3 Sensitivity Adjustment Using an External Weight

This function adjusts the sensitivity of 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 untilAND GX AE GX A GX AWP GX AWP Series Multi Function Balance - icon8 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 sensitivity adjustment, if GLP output is set, a “sensitivity adjustment report” is output or stored in data memory.
  7. The display automatically returns to the 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”.

4-5 Other Display

AND GX AE GX A GX AWP GX AWP Series Multi Function Balance - Display22Advice

This is the automatic sensitivity adjustment notice (the indicator blinking).
If the balance is not used for several minutes with this indicator blinking, the balance automatically performs sensitivity adjustment using the internal mass. The blinking period depends on the operating environment. The balance can be used when this indicator is blinking, but we recommend that you perform sensitivity adjustment before weighing.
