Enter the password (default 1234) followed by pressing the ENTER softkey.
Enter the calibration Menu and then select 'CALIBRATION MODE [OFF]'
If a temperature warning message appears, leave the multimeter to warm up for longer, as this is indicating that the multimeter is not yet thermally stable at the normal operation temperature.

The BLUE shift key indicates that calibration mode is presently active, along with the RED C in the bottom right of the screen
