- Adjust the adjustable feet at the bottom of the scale until the air bubble is centered within the circle of the spirit level.
6. Operating Instructions
6.1 Power On/Off
Press the [ON/OFF] button to turn the scale on or off. The display will show a self-test sequence before settling at zero.
6.2 Basic Weighing
- Ensure the scale is level and powered on, displaying '0.0g'.
- Gently place the item to be weighed on the center of the weighing pan.
- Wait for the reading to stabilize (indicated by a stable icon on the display, if available).
- Read the weight displayed on the LCD.
6.3 Tare Function
The Tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.
- Place an empty container on the weighing pan.
- Press the [TARE] button. The display will reset to '0.0g'.
- Add the items to be weighed into the container. The display will show the net weight of the items.
6.4 Counting Function
The Counting function allows you to count a large number of identical items based on a sample weight.
- Place a known quantity of items (e.g., 10, 20, 50 pieces) on the weighing pan.
- Press the [COU] button. The display will prompt you to select the sample quantity.
- Use the appropriate buttons (refer to specific model instructions if available, typically TARE or UNIT) to select the sample quantity (e.g., '10', '20', '50').
- Press [COU] again to confirm the sample. The display will now show the count of items.
- Add more items to the pan, and the scale will display the total count.
6.5 Unit Conversion
To switch between available weighing units (e.g., grams, kilograms, pounds, carats), press the [UNIT] button repeatedly until the desired unit is displayed.
6.6 External Calibration
Calibration ensures the accuracy of your scale. It should be performed periodically or if you suspect inaccurate readings. An external calibration weight (not included) is required.
- Ensure the scale is powered on and stable, with nothing on the pan.
- Press and hold the [CAL] button until the display shows 'CAL' or a calibration prompt.
- The display will then indicate the required calibration weight (e.g., '10000g' for 10kg).
- Carefully place the specified calibration weight onto the center of the weighing pan.
- Wait for the scale to process the calibration. The display will typically show 'PASS' or return to '0.0g' once calibration is complete.
- Remove the calibration weight.

7. Maintenance
7.1 Cleaning
- Always disconnect the scale from the power source before cleaning.
- Wipe the weighing pan and scale body with a soft, slightly damp cloth.
- For stubborn dirt, a mild detergent can be used, but ensure no liquid enters the scale's internal components.
- Do not use abrasive materials, solvents, or harsh chemicals, as these can damage the finish and internal parts.
7.2 Storage
- When not in use for extended periods, store the scale in a dry, dust-free environment.
- Avoid placing heavy objects on the weighing pan during storage.
- If the scale has a rechargeable battery, ensure it is charged periodically to maintain battery health.
