5 Maintenance and Calibration
5.1 Maintenance
After use, please keep the instrument body clean, do not let oil or other substances
infiltrate into the body and the screen, not to damage the instrument.
Please do not forget to remove the load after measurement. Applying a load for a
long time may affect the accuracy of the instrument.
Unless there is a special need, please do not switch off the Auto Power, because it
can reduce the consumption of the battery and extend batteries life.
5.2 Charging
When the batteries are low, the icon “
” will be displayed. The batteries should be
charged immediately.
Connect the gauge and the charger using the USB cable, and then connect the
charger with AC socket to start charging.
It takes about 3~4 hours for completely charging.
5.3 Calibration
Because of the sensor’s material performance or the influence of external factors,
there may be errors in a certain range after being used a period of times.
The force gauge can be sent to us for a specialized testing and for calibration.
If you have some standard force weights or the other standard load and some test
stand, you may calibrate it also on your own, as shown below:
❶Mount the force gauge to a test stand or fix it anywhere else
❷Remove the tare by using the key
