If errors are detected during a measurement or calibration sequence, a message will be displayed
and one or more error icons appear.
Keyboard functions:
On/Clear •Push shortly to activate the instrument.
•When switched on it clears all selected operations.
•Displays the last measurement result.

Off •Terminates all activity, saves changed values and powers off.
Scroll up •Open the menu, scroll through menus
•Increment/scroll edit values.
Scroll down •Open the menu, scroll through menus
•Decrement/scroll edit values.
Calibration •Open Instrument calibration menu, select/change settings.
