5. Operating Instructions
5.1 Power On/Off
Press the ON/OFF button to turn the scale on or off.
5.2 Basic Weighing
- Ensure the scale is on and displays "0.0000 kg" (or current unit).
- Place the item(s) to be weighed on the center of the weighing platform.
- Read the weight displayed in the "WEIGHT" section of the LCD.
5.3 Unit Conversion
The scale supports multiple units: grams (g), kilograms (kg), and pounds (lb). To switch between units, press the kg/lb button.

5.4 Tare Function
To weigh items in a container without including the container's weight:
- Place the empty container on the weighing platform.
- Press the TARE button. The display will reset to zero.
- Add the items to be weighed into the container. The display will show only the net weight of the items.
5.5 Counting Function
The scale offers two methods for counting parts:
Method 1: Known Unit Weight
- Enter the known unit weight of a single item using the numeric keypad.
- Press the UNIT W.T. button to confirm.
- Place the items to be counted on the platform. The "QUANTITY" display will show the count.
Method 2: Sampling
- Place a sample quantity (e.g., 10, 20, 50, 100 pieces) of the items on the platform.
- Enter the exact number of sample pieces using the numeric keypad.
- Press the SMPL button to confirm the sample. The scale will calculate the unit weight.
- Add the remaining items to be counted. The "QUANTITY" display will show the total count.

5.6 Accumulation Function
To accumulate total weight and quantity from multiple weighing operations:
- After a weighing or counting operation, press the M+ button. The current weight and quantity will be added to the total.
- Repeat for subsequent items.
- To view the accumulated total, press the MR button. The display will show total weight, total number of operations, and total quantity.
- To clear the accumulation memory, press MC.

5.7 Alarm Settings (Weight & Quantity)
The scale allows setting custom thresholds for weight and quantity. An audible alarm will sound if these thresholds are exceeded.
- Press the ALARM button.
- Use the numeric keypad to enter the desired upper limit for weight or quantity.
- Press ENTER to save the setting.
- The alarm will activate if the measured value goes above the set limit.

5.8 RS232 Connectivity
The integrated RS232 interface allows direct connection to printers, computers, or POS systems for data management. This enables immediate export of weight or quantity data, streamlining inventory management and improving efficiency.
Note:
The scale uses a null modem serial connection (TX/RX inverted). Data output requires a computer application (such as HyperTerminal or STC ISP) for proper communication.
