2. Press the "PCS" button and hold it until "25", "50", "75", or "100" appears on the display. This indicates the sample quantity.
3. Place the corresponding number of sample items (e.g., 25 items for "25") on the weighing platform.
4. Press "PCS" again to confirm the sample quantity. The display will show "PASS" and then the number of items.
5. You can now add more items to be counted. The display will show the total count.
6. To exit counting mode, press "MODE" or "M" key.

5. Backlight Function (LIGHT)

Press the "LIGHT" button to turn the display backlight on or off. (Note: This function may not be available on all product versions.)

Calibration

Calibration ensures the accuracy of your scale. It is recommended to calibrate the scale periodically or if you notice inconsistencies in readings. You will need a precise calibration weight (e.g., 2000g) for this process.

1. Turn on the scale. Ensure the weighing platform is empty and stable.
2. Press and hold the "MODE" button until "CAL" appears on the display.
3. Release the "MODE" button. The display will then show the required calibration weight (e.g., "2000g").
4. Carefully place the exact calibration weight (e.g., 2000g) onto the center of the weighing platform.
5. The display will show "PASS" and then return to normal weighing mode, indicating successful calibration.
6. Remove the calibration weight.

Note: Ensure to use the same product specifications of the standard weight to calibrate.

Instructions for operation and calibration are conveniently located on the scale's protective lid.
