10.3 Switch off the hand-held meter Display illumination If a key is not pressed for two minutes, the hand-held meter reduces display brightness to protect battery life. The illumination switches back on the next time any key is pressed. If a key is not pressed for five minutes, the hand-held meter switches off automatically. The device can be switched on or off manually at any time using [ON/OFF]. -

How can faulty calibration be resolved? Faulty calibration can only be resolved by a precise re-calibration. Where the conditions for precise calibration are lacking, this can be mitigated by a reset to factory settings. This function gives the user the option to reset the sensors to their initial position, however, this will not correspond to the current behaviour status of the sensors. -
