Calibration Counter / Tamper detector
An internal totaliser counts each calibration. The ‘CAL XX’ value appears for a
second or two after you switch the meter on. The number starts at 00 and can go
up to FF (255 counts). It doesn’t count changes of setpoints, or changes of filter
value or count-by value . It stores the total in non-volatile memory which can’t
be reset, so is useful for keeping track of the meter’s calibration history.

The reset command clears the accumulated total. It may be accessed either
from the front panel or by external contact closure command.
