- Press the HOLD button again to release the reading and return to live weighing.
Peak Hold Function
The Peak Hold function captures and displays the maximum weight detected during a measurement, useful for non-stationary loads or pull strength tests.
- To activate Peak Hold: With the scale turned off, press and hold the TARE button, then press the ON/OFF button. Release both buttons when "0" appears. The scale is now in Peak Hold mode.
- Apply force or weigh the item. The display will show the maximum weight reached. If the weight is removed, apply a little force to make the peak reading reappear.
- To reset the peak reading, turn the scale off and then on again. The Peak Hold mode will remain active.
- To deactivate Peak Hold: With the scale turned off, press the TARE button, then press the ON/OFF button. This will return the scale to normal weighing mode.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scale does not turn on. | Dead or incorrectly installed batteries. | Check battery polarity or replace with new AAA batteries. |
| Inaccurate readings. | Scale not tared, unstable surface, or needs calibration. | Ensure scale is stable. Use Tare function before weighing. Perform calibration if necessary. |
| Display shows "O-Ld" (Overload). | Weight exceeds maximum capacity (660 lbs / 300 kg). | Remove excess weight immediately to prevent damage. |
| Numbers climbing/fluctuating rapidly. | Unstable load, strong air currents, or internal issue. | Ensure the item is stable. Use the Peak Hold function for non-stationary loads. If problem persists, contact customer support. |
