Solution
My device turns itself off.
1.
Check that the battery percentage is not at 0%.
Put the device on charge
2.
The Centor First II will automatically shut off after
15 minutes if no button is pressed.
My device is blocked, the force does
not vary anymore.
Turn off and restart your instrument using the on/off key.
My device does not display the
measurement screen but an
information page with Offset in red.
If the offset value is greater than 20%, the device cannot
measure. Turn off your device and remove the load
applied to the sensor. Then turn on your device.
If no load is applied to the sensor, then the sensor is
deformed. You must then return your device to us for
replacement of the sensor.
