4.2 Basic Weighing

• Ensure the scale is on and displaying "0.00g".
• Gently place the item to be weighed onto the center of the weighing platform.
• The weight will be displayed on the LCD screen.

4.3 Tare Function

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

2. Press the T (Tare) button. The display will reset to "0.00g".
3. Place the items to be weighed into the container. The display will show only the net weight of the items.

4.4 Unit Conversion

The scale supports multiple weighing units.

• While the scale is on, press the M (Mode) button to cycle through the available units (e.g., g, oz, ozt, dwt, ct, gn).
• Select the desired unit for your measurement.

4.5 Piece Counting (PCS)

This mode is useful for counting multiple small, identical items.

1. With the scale on and displaying "0.00g", place a sample quantity of items (e.g., 25, 50, 75, or 100 pieces) on the platform.
2. Press and hold the PCS button until "PCS" appears on the display.
3. Press the M button to select the sample quantity you placed (e.g., 25, 50, 75, 100).
4. Press the PCS button again to confirm. The scale is now calibrated for piece counting.
5. Add more items to the platform, and the display will show the total count.

5. Calibration

Calibration is not required before first use. Only calibrate if the scale is not weighing properly.

Standard Calibration Procedure:

1. Under weighing status, press and hold the M button for a few seconds. The display will show the default calibration weight or the previous record.
2. If you do not have the same calibration weight, press the M button again to choose from other available weights. Select the one you have.
3. After confirming the calibration weight, press the ON/OFF button. The display will show "CAL", and the required calibration weight will be displayed.
4. Place the required calibration weight onto the platform.
5. Press the ON/OFF button again. The LCD will display "PASS", indicating automatic correction is complete.
6. Remove the calibration weight to use the scale. For best accuracy, use the maximum calibration weight available.

Calibration for "OUT2" Error:

If the scale displays "OUT2" when turned on, follow these steps:

1. Turn off the scale.
2. Press the ON/OFF button and the M button simultaneously for a few seconds until a group of weight digits shows on the screen.
3. Press the ON/OFF button again. The word "CAL" will flash, and a specific weight will be displayed.
4. Place the required calibration weight onto the platform.
5. Press the ON/OFF button. The LCD will display "PASS", indicating automatic correction.
6. Remove the calibration weight to use the scale.

6. Maintenance

• Cleaning: Wipe the scale with a slightly damp cloth. Do not use abrasive cleaners or immerse the scale in water.
• Storage: Store the scale in a clean, dry environment away from extreme temperatures and humidity. Keep it away from dust and direct sunlight.
