4. Operating Instructions
The scale features simple, single-button operation.
- Power On: Press the 'ON/TARA/OFF' button to turn on the scale. The display will show a self-test sequence and then settle at '0.000 kg'.
- Weighing: Place the item to be weighed directly onto the weighing platform. The weight will be displayed in kilograms (kg).
- Tare Function: To weigh items in a container, first place the empty container on the platform. Press the 'ON/TARA/OFF' button briefly. The display will reset to '0.000 kg'. You can now add items to the container, and only the net weight of the items will be displayed.
- Extendable Terminal: The display terminal can be extended up to 30 mm, providing more weighing surface without obstructing the display and improving access to connectors.
- Power Off: Press and hold the 'ON/TARA/OFF' button for a few seconds to turn off the scale. The integrated Auto-Off function will automatically power down the scale after a period of inactivity to save energy.
