Reset Command
The reset command clears any stored peak or valley data, any tared offsets and any in-flight
compensation data. It may be accessed either from the front panel or by external contact
closure command.
Front Panel key reset command
1) Link terminal 7 to terminal 10 (not necessary if MEM-08 option fitted)
2) Set calibration lockout switch ‘ON’
3) Press Down Arrow key to reset display.
For Tare reset, you must press the Tare button AND the Reset button together.
For Peak/Valley reset, you must activate the reset key while a peak or valley value is being
displayed.
Remote contact closure resetting
1) Connect a normally-open contact closure switch between terminals 7 and 10
2) Set calibration lockout switch 3 ‘ON’
Calibration Counter / Tamper detector
An internal totaliser counts each calibration. The ‘CAL XXX’ value appears for a second or two
after you switch the meter on. The number starts at 00 and can go up to FFF . It counts all
changes made to the meter’s calibration . 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.
You can ask the meter to repeat its summary at any time if you press the two outer buttons for 3
seconds.
