Introduction

This quick start guide describes the basic functions and operations of the balance (FZ-i / FX-i / FZ-i WP / FX-i WP / FZ-GD / FX-GD series).

The functions and operating procedures of the balance are explained in details in the “FZ-i / FX-i / FZ-i WP / FX-i WP / FZ-GD / FX-GD SERIES Precision Balance INSTRUCTION MANUAL”. This manual can be downloaded from our website https://www.aandd.jp

Installation and Precautions

The balance is a precision instrument. Unpack it carefully. It is recommended to keep the packing materials to be used for transporting the balance in the future.
The packing contents depend on the balance model. See the following illustrations to confirm that everything is included.

Cautions

• Verify that the AC adapter type is correct for your local voltage and receptacle type.
• Use the dedicated AC adapter specified for the balance.
• Do not use the AC adapter provided with the balance for models that are not considered compatible with the AC adapters.
• If you use a wrong AC adapter, the balance and other equipment may not operate properly.

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 (An anti-vibration table or stone table is ideal).
• Install the balance on a horizontal table and check that it is not tilted.
• 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. Refer to the next page “How to adjust 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 “8. CALIBRATION” in the instruction manual.

With the FZ-i WP / FX-i WP 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 direct jet of water”. Washing the balance with strong water pressure or submerging it in water, may cause water to seep inside the balance and cause a malfunction.
• When installing and using the balance under conditions requiring dustproof and waterproof performances, 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 (AX-KO2737-500) 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.

How to adjust the bubble spirit level

When the bubble is off to the left:
Turn the leveling foot on the front right in the clockwise direction.

When the bubble is off to the right:
Turn the leveling foot on the front left in the clockwise direction.

When the bubble is off to the backward position:
Turn both leveling feet on the front in the clockwise direction at the same time.

When the bubble is off to the forward position:
Turn both leveling feet on the front in the counter clockwise direction at the same time.

Calibration

Calibration Using the Internal Mass
(One-Touch Calibration, FZ-i / FZ-iWP / FZ-GD 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.  Place the accessory breeze break on the balance and press the 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 report.
5. The balance will automatically return to weighing mode after calibration

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 key for 2 seconds until is displayed, and then release the key.

3. The balance displays .

   • If you want to change the calibration weight, press the key and go to step 4. Refer to “8. CALIBRATION” in the instruction manual for selectable calibration weights.
   • If you use the calibration weight value stored in the balance, go to step 5.

4. Specify the calibration weight value as follows:
    key To switch the display condition to “All of the segments blinking” (target weight selection mode) or “The last two digits blinking” (value adjustment mode).
    key (To increase the value)
    key (To decrease the value)
   To select the calibration weight or adjust the value.
    key To store a new weight value. Even if the AC adapter is removed, the data is maintained in non-volatile memory.
   key To cancel the operation (return to ).

5. Confirm that there is nothing on the pan and press the key. The balance measures the zero point and displays the measured value. Do not allow vibration or drafts to affect the balance.

6. Place the calibration weight on the pan and press the  key. The balance measures the calibration weight and displays the measured value. Do not allow vibration or drafts to affect the balance.

7. Remove the weight from the pan.

8. After the calibration, if the “GLP output” is set, the balance outputs a “sensivity adjustment report”.

9. The balance will automatically return to the weighing mode.

10. Place the calibration weight on the pan again and check if the value is within the range (set value ± 2 digits). If it is out of the range, pay attention to the surrounding environment and start again from step 1.

Error Codes
