Choose a location that is stable, flat, and free from vibrations, drafts, and direct heat sources. Ensure adequate space around the balance for operation and ventilation.

5.2 Leveling the Balance

1. Place the balance on your chosen surface.
2. Locate the level bubble, usually found near the front or side of the balance.
3. Adjust the four adjustable feet by turning them clockwise or counter-clockwise until the air bubble is centered within the red circle of the level indicator.

6. Operating Instructions

6.1 Power On/Off

• Press the ON/OFF button to turn the balance on.
• Press and hold the ON/OFF button to turn the balance off.

6.2 Unit Conversion

The balance supports 13 unit conversions. To change the weighing unit:

• Press the UNIT button repeatedly to cycle through available units: g, ct, oz, ozt, N, lb, dr, GN, dwt, %, tlT, T, TAR.
• The selected unit will be displayed on the LCD screen.

6.3 Tare/Zero Function

The Tare/Zero function allows you to subtract the weight of a container or to reset the display to zero before adding an item.

1. Place an empty container on the weighing pan.
2. Wait for the reading to stabilize.
3. Press the TARE/ZERO button. The display will show "0.00g" (or the current unit), and the tare indicator may appear.
4. You can now add items to the container, and only their net weight will be displayed.

6.4 Counting Function (PCS)

This function allows you to count a large number of small, identical items.

1. Place a sample quantity of items (e.g., 10, 20, 50, or 100 pieces) on the weighing pan.
2. Press and hold the PCS button until the display shows a sample size (e.g., "P-25").
3. Press the UNIT button to select the sample size that matches the number of items you placed on the pan.
4. Press PCS again to confirm. The display will now show the count of the sample.
5. Remove the sample and place the bulk quantity of items you wish to count. The display will show the total count.

6.5 Calibration (CAL)

Regular calibration ensures the accuracy of your balance. It is recommended to calibrate the balance periodically or if you suspect inaccurate readings.

1. Ensure the balance is on a stable surface and level.
2. With nothing on the weighing pan, press and hold the CAL button until "CAL" appears on the display.
3. The display will then show the required calibration weight (e.g., "3000g").
4. Carefully place the specified calibration weight (e.g., 3000g) onto the center of the weighing pan.
5. Wait for the display to stabilize and show "PASS" or return to normal weighing mode (e.g., "0.00g").
6. Remove the calibration weight. The balance is now calibrated.
