6. Operating Instructions

6.1. Basic Weighing

1. Ensure the balance is on a level surface and powered on.
2. Wait for the display to show "0.00g" or the selected unit.
3. Gently place the item to be weighed onto the center of the weighing pan.
4. Read the stable weight displayed on the LCD screen.
5. Remove the item from the pan.

6.2. Tare Function

The tare function allows you to weigh items in a container by subtracting the container's weight.

1. Place the empty container on the weighing pan.
2. Press the TARE/ZERO button. The display will reset to "0.00g".
3. Place the items to be weighed into the container. The display will show the net weight of the items.

6.4. Calibration

Regular calibration ensures accuracy. Use a known calibration weight (e.g., 2000g) for this process.

1. Ensure the balance is powered on and the weighing pan is empty.
2. Press and hold the CAL button until "CAL" appears on the display, then release.
3. The display will show the required calibration weight (e.g., "2000g").
4. Carefully place the specified calibration weight onto the center of the weighing pan.
5. Wait for the display to show "PASS" or return to normal weighing mode with the correct weight displayed.
6. Remove the calibration weight. The balance is now calibrated.
