3.2 Power Connection

1. Connect the provided power cord to the scale's power input and then to a standard 110V AC power outlet. The scale supports 100-240V input.
2. If using optional battery power, ensure the battery (6v4ah lead acid rechargeable battery, size 3.85"x2.67"x1.77") is correctly installed in the battery compartment.
3. Turn on the scale using the power switch, typically located on the underside or side of the unit.

3.3 Initial Calibration

The scale is factory-calibrated. However, for optimal accuracy, especially after initial setup or relocation, external calibration is recommended. Refer to the 'External Calibration' section in the full user manual for detailed steps.

4. Operation

4.1 Basic Weighing

1. Ensure the scale is powered on and displays '0.00'.
2. Gently place the item to be weighed on the center of the weighing pan.
3. Read the stable weight displayed on the LED screen.

4.2 Tare Function

The Tare function allows you to subtract the weight of a container or packaging, so only the net weight of the contents is measured.

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

4.3 Unit Conversion

To change the weighing unit (g, kg, lb, oz):

• Press and hold the MC/UNITS button for approximately 3 seconds.
• The unit will cycle through the available options. Release the button when the desired unit is displayed.

4.4 Counting Function

The scale supports both quantity sampling and weight sampling modes for counting.

1. Place a known number of sample items (e.g., 10, 20, 50, 100) on the pan.
2. Use the PIECE COUNTING or WEIGHT COUNTING button and follow the on-screen prompts to input the sample quantity.
3. Once the sample is set, remove the sample and place the bulk items on the pan. The scale will display the total count.
