Setup and Installation
Unpacking:
Carefully remove all components from the packaging. Verify that the following parts are present:
- Analytical Balance Unit
- Stainless Steel Weighing Pan
- Power Adapter
- User Manual (this document)
Placement:
Place the balance on a stable, level surface that is free from vibrations, drafts, and direct sunlight. Ensure the surface is clean and dry to prevent interference with measurements.

Operating Instructions
Control Panel Overview:
Image: The control panel of the analytical balance, detailing the function of each button: Power, Calibration (CAL), Piece Counting (PCS), Print, Unit Conversion (UNIT), and Tare/Zero.
- Power Button: Used to turn the balance ON or OFF.
- CAL Button: Initiates the calibration process.
- PCS Button: Activates the piece counting function for counting multiple identical items.
- PRINT Button: Sends the current weighing data through the RS232 interface.
- UNIT Button: Cycles through the available weighing units (g, lb, ozt, oz, ct).
- TARE Button: Zeros the display or tares the weight of a container.
Basic Weighing:
- Ensure the balance is level and powered on.
- Wait for the display to stabilize and show "0.00g".
- Carefully place the item to be weighed on the center of the stainless steel pan.
- Read the stable weight displayed on the LCD.
Unit Conversion:
To change the weighing unit, press the UNIT button repeatedly. The display will cycle through grams (g), pounds (lb), troy ounces (ozt), ounces (oz), and carats (ct).

Tare Function:
To weigh an item within a container, first place the empty container on the weighing pan. Press the TARE button to zero the display. Then, add the item to the container; the display will show only the net weight of the item, excluding the container's weight.
Calibration:
The balance features an automatic calibration function. For precise calibration, it is recommended to perform multi-point calibration using external calibration weights. Detailed steps for this procedure are available in the comprehensive user manual.
For more detailed calibration procedures, please refer to the official user guide: CGOLDENWALL Analytical Balance User Guide (PDF).
RS232 Interface:
The RS232C output interface enables seamless data transfer. Connect the balance to a compatible computer or printer using an RS232 cable. Press the PRINT button to send the current weighing data to the connected device.

Maintenance
Cleaning:
To clean the balance and weighing pan, use a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface or internal components. Ensure no liquids enter the balance housing.
Storage:
When the balance is not in use, store it in a clean, dry environment. Protect it from extreme temperatures, high humidity, and direct sunlight. Keep the weighing pan clean and free of any debris.
Regular Checks:
Periodically verify the level of the balance using the built-in level bubble. Recalibrate the balance as needed to ensure consistent accuracy, especially after relocation or significant temperature changes.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows "Err-2" | Weighing data lost, requires multi-point calibration. | Perform multi-point calibration using external weights as per the full user manual. |
| Inaccurate readings | Balance not level, vibrations, drafts, or needs calibration. | Ensure balance is level, placed on a stable surface, away from drafts. Recalibrate the balance. |
| Display not turning on | No power, faulty power adapter, or dead batteries. | Check power connection. Replace batteries if using battery power. Try a different power outlet. |
