Setup and Calibration

Initial Setup

1. Place the scale on a hard, flat, and stable surface, away from vibrations or air currents.
2. Ensure the windscreen is properly installed.
3. Power on the scale using either AAA batteries or the USB cable.

Calibration

Calibration is essential for accurate measurements. Perform calibration regularly or if you suspect inaccuracies.

1. Turn the scale ON. Wait for the display to show "0.000g".
2. Press and hold the "M" (Mode) key until "CAL" appears on the display, then release.
3. Press the "M" key again. The display will flash the required calibration weight (e.g., "100.000g").
4. Gently place the provided 100g calibration weight onto the center of the weighing surface.
5. Wait for the display to show "PASS" and then return to "0.000g". This indicates successful calibration.
6. Remove the calibration weight. The scale is now ready for use.

Tare Function

The Tare function allows you to subtract the weight of a container, so you only measure the net weight of its contents.

1. Place an empty container (e.g., the plastic weighing pan) on the weighing surface.
2. Press the "T" (Tare) key. The display will reset to "0.000g".
3. Add the items you wish to weigh into the container. The display will show only the weight of the items.
4. Note: Some users have reported inconsistencies with the TARE button. If you experience issues, ensure the scale displays "0.000" with nothing on it before placing your container.

Counting Function (PCS)

The PCS function allows you to count multiple small items of uniform weight.

1. Turn on the scale and wait for "0.000g".
2. Press and hold the "P" (PCS) button until "PCS" flashes on the display.
3. Press the "M" (Mode) button to select a sample quantity (e.g., 25, 50, 75, or 100 pieces).
4. Place the selected sample quantity (e.g., 25 pieces) of your item onto the weighing surface.
5. Press the "P" button once to confirm the sample. The display will show the sample quantity.
6. Remove the sample. Now, when you place any quantity of the same item on the scale, it will display the count.
7. Attention: For accurate counting, the items must have a consistent weight.

2. While holding "T", press the "On-off" key to turn the scale ON. Continue holding "T".
3. The display will show a number (e.g., "120"), indicating the current auto-off time in seconds.
4. Press the "M" (Mode) key to cycle through available auto-off times (e.g., 60, 120, 180 seconds, or "00" for no automatic shut-off).
5. Once you have selected your desired auto-off time, press the "T" key briefly to confirm. The display will show "PASS" and then return to normal weighing mode.
