Removing calibrations
This function will completely remove zero deviation and two-point
calibrations for all modes.
This function will restore the device's functionality in case of
incorrect calibration, but for accurate measurements it needs to
be calibrated again.
To remove calibrations, when the display shows dashes
, press and hold the button for 3
seconds.
The display will show "-CL-" and a sound signal will be emitted.
The calibrations have been erased.
