6. Operating Instructions
6.1 Basic Weighing
- Ensure the scale is powered on and the display shows zero.
- Carefully place the item to be weighed onto the center of the weighing pan.
- Wait for the reading to stabilize. The weight will be displayed on the LCD.
- Remove the item from the pan. The display should return to zero or a negative value if tare was applied.
6.2 Taring (Zeroing)
To weigh an item in a container, you can tare the weight of the container:
- Place the empty container on the weighing pan.
- Press the [TARE] button. The display will show zero, indicating the container's weight has been tared.
- Place the item to be weighed into the container. The display will show only the net weight of the item.
- To clear the tare, remove the container and item, then press [TARE] again.
6.3 Unit Selection
The scale can display weight in kilograms (kg) or pounds (lb).
- Press the [UNIT] button to cycle through available weighing units.
- The selected unit will be indicated on the display.
6.4 Hold Function (Dynamic Weighing)
The programmable hold function is useful for weighing unstable samples, such as animals, or in environments with slight movement.
- Place the unstable item on the platform.
- Press the [HOLD] button. The scale will average the weight over a short period and display a stable reading.
- Press [HOLD] again to exit the function.
6.5 Auto-Off Function
To conserve battery life, the scale features an auto-off function that powers down the device after a period of inactivity. Refer to the full manual for instructions on how to enable or disable this feature and adjust its timing.
