5. Operation
5.1 Basic Weighing
- Ensure the scale is on a level surface and powered on, displaying "0.000" or "0.00" in the selected unit.
- Gently place the item to be weighed onto the center of the stainless steel platform.
- Wait for the display to stabilize. The weight will be shown in the current unit.
5.2 Unit Conversion
The scale supports multiple weighing units (kg, lb, ST, pcs). To change the unit:
- Press the UNIT button repeatedly to cycle through the available units (kg, lb, ST). The active unit will be indicated on the display.
5.3 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 measured.
- Place the empty container onto the weighing platform. The display will show its weight.
- Press the TARE button. The display will reset to "0.000" (or "0.00"), indicating the container's weight has been tared out.
- Now, place the items to be weighed into the container. The display will show only the weight of the items.
- To clear the tare, remove the container from the platform and press the TARE button again.
5.4 Piece Counting Function
The piece counting function allows you to count a large number of identical items quickly.
- Ensure the scale is at zero.
- Press the MODE button until "pcs" (pieces) is indicated on the display.
- Place a known sample quantity of items (e.g., 10, 20, 50, or 100 pieces) onto the platform.
- Use the ZERO or UNIT buttons (refer to specific model instructions if different) to select the sample quantity you placed. Confirm the sample quantity.
- Once the sample is set, remove the sample and then place the bulk quantity of items onto the platform. The display will show the total count of items.
- To exit counting mode, press the MODE button again until a weight unit (kg, lb, ST) is displayed.
6. Maintenance
6.1 Cleaning
- Always disconnect the scale from the power supply before cleaning.
- Wipe the stainless steel platform and the scale body with a soft, damp cloth. A mild detergent can be used if necessary.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface and electronic components.
- Ensure no liquid enters the interior of the scale, especially around the display and buttons.
- Dry the scale thoroughly after cleaning.
6.2 Battery Care
- To prolong battery life, avoid completely discharging the battery frequently.
- If the scale will not be used for an extended period, charge the battery periodically (e.g., every 3 months) to maintain its capacity.
