Setup
1. Unpacking and Placement
Carefully remove the balance from its packaging. Place the balance on a firm, level, and vibration-free surface. Ensure it is away from direct sunlight, drafts, and sources of heat or cold that could affect accuracy.
2. Power Connection
The balance can be powered by either the AC adapter or 4xDC1.5V batteries.
- AC Power: Connect the provided AC adapter to the power input port on the rear of the balance, then plug it into a suitable AC 100V-240V power outlet.
- Battery Power: Open the battery compartment on the underside of the balance and insert 4xDC1.5V batteries, ensuring correct polarity.

3. Leveling the Balance
Accurate measurements require the balance to be perfectly level. Adjust the leveling feet located at the bottom of the balance until the bubble in the bubble level indicator is centered within the circle.

4. Warm-up Time
For optimal accuracy, allow the balance to warm up for at least 30 minutes after initial power-on or after a power loss. This stabilizes the internal components.
Operating Instructions
1. Power On/Off
- Press the Power button () to turn the balance on.
- Press and hold the Power button for a few seconds to turn the balance off.
2. Unit Conversion
The balance supports 19 different measurement units. Press the UNIT button to cycle through the available units (e.g., g, kg, ct, oz, lb, etc.).

3. Tare Function
To subtract the weight of a container, place the empty container on the weighing pan and press the TARE/CAL button. The display will reset to zero, allowing you to weigh only the contents.
4. Calibration
Recalibration is recommended after moving the balance or if accuracy is in question. Refer to the specific calibration procedure in the full manual for your model. Typically, this involves pressing and holding the TARE/CAL button and following on-screen prompts with a known calibration weight.

5. Counting Function (COU)
The balance can count items of uniform weight. To use this function:
- Place a known quantity of items (e.g., 10, 20, 50, 100, 150, 200, 250, or 500) on the pan.
- Press the COU button.
- Select the corresponding sample quantity using the UNIT button, then confirm.
- The balance will now display the count of items placed on the pan.

6. RS232 Communication
The RS232 interface allows for serial data exchange with a computer or printer. This is useful for recording weighing results and minimizing manual data entry errors. Consult your computer or printer's manual for specific connection and software requirements.
Maintenance
- Cleaning: Wipe the balance with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the internal components.
- Storage: When not in use, cover the balance with the provided dust protective cover. Store in a dry, stable environment.
- Battery Replacement: If using batteries, replace all four batteries when the low battery indicator appears on the display.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows "Err" or unstable readings | Overload, unstable surface, drafts, or magnetic interference. | Remove excess weight. Ensure balance is level and on a stable surface. Relocate away from drafts or magnetic fields. |
| Balance does not turn on | No power, dead batteries, or faulty AC adapter. | Check AC adapter connection. Replace batteries if using battery power. |
| Inaccurate readings | Not leveled, not warmed up, needs calibration, or environmental factors. | Level the balance. Allow warm-up time. Perform calibration. Ensure stable environment. |
| RS232 communication failure | Incorrect cable, driver issues, or software settings. | Verify cable connection. Install necessary drivers. Check software settings. |
