4.2 Basic Weighing Operation

1. Power On: Press the power button (if available, otherwise connect power). The display will perform a self-test and then show zero.
2. Zeroing: If the display does not show zero when the scale is empty, press the ZERO button to reset the reading to zero.
3. Weighing: Place the item to be weighed on the scale platform. The display will show the weight. Wait for the STABLE indicator to light up for an accurate reading.
4. Unit Conversion: To switch between kilograms (kg) and pounds (lb), press the UNIT button (or equivalent, typically labeled 'kg/lb' or integrated into a 'FUNC' menu).

4.3 Tare Function

The Tare function allows you to subtract the weight of a container or packaging, so only the net weight of the contents is displayed.

1. Place the empty container on the scale platform.
2. Press the TARE button. The display will reset to zero, and the TARE indicator will light up.
3. Add the items to be weighed into the container. The display will show the net weight of the items.
4. To clear the tare, remove the container from the scale and press the TARE button again.

4.4 Accumulation Function (ACCUM)

The accumulation function allows you to sum multiple weight readings.

1. Weigh the first item. Ensure the STABLE indicator is on.
2. Press the ACCUM button. The weight will be added to the total, and the ACCUM indicator will light up.
3. Remove the item and place the next item on the scale.
4. Repeat step 2 for each subsequent item.
5. To view the total accumulated weight or clear the accumulation, refer to the specific instructions in the full product manual or use the FUNC button to navigate options.

5. Maintenance

• Cleaning: Wipe the indicator with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the device.
• Battery Care: The built-in rechargeable battery should be charged regularly. If the "LOW VOLTAGE" or "Low battery" indicator appears, connect the indicator to AC power. For long-term storage, charge the battery fully and store in a cool, dry place.
• Calibration: Periodic calibration may be required to maintain accuracy, especially after relocation or prolonged use. Refer to advanced settings in the full manual or contact technical support for calibration procedures.
• Environmental Conditions: Operate and store the indicator within recommended temperature and humidity ranges to ensure optimal performance and longevity.

6. Troubleshooting

• Indicator does not power on:
  • Check if the power adapter is securely connected to both the indicator and the power outlet.
  • Ensure the power outlet is functional.
  • If using battery power, ensure the battery is charged. Connect to AC power to charge.
• Display shows "LOW VOLTAGE" or "Low battery":
  • The built-in battery needs charging. Connect the indicator to AC power using the provided adapter.
• Inaccurate readings or unstable display:
  • Ensure the scale platform is stable and level.
  • Check all load cell connections for security and proper wiring.
  • Verify that no external vibrations or air currents are affecting the scale.
  • Perform a zero operation before weighing.
  • Consider recalibration if the issue persists.
• Display shows error codes:
  • Refer to the full product manual for a list of specific error codes and their meanings. Common issues might relate to load cell overload or connection problems.
