MANUAL CALIBRATION (MANUAL CAL)
This sequence is not recommended to be followed by the user. The manual
cal sequence requires values to be entered manually. Re-calibrate is a
more accurate operation. This provision is of more practical use to a
service engineer.

) key again and then select YES or NO
using the

‘

↵ ↵↵ ↵↵
) key whilst ‘YES’ is displayed to return the
instrument back to its factory settings. Press the
‘
ENTER' (
↵ ↵↵ ↵↵
) key whilst
‘NO’ is displayed to return to the ‘Recall Factory’ screen on the
Calibration menu.
