Features - contd.
Automatic Zero-Drift Compensation
This feature is useful in applications where your meter reads zero most of the
time. It cancels long-term zero drift caused by ageing, temperature change, etc.
If the reading is within 7 counts of zero for around 100 seconds, the reading will
go to zero without changing basic calibration. The correction is
not stored
when the meter is switched off and is cleared if you press the front panel
RESET button for more than 3 seconds. To activate this feature, set the display
value at 0% input to MINUS ZERO ( -0)
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.
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 (Not with MEM-08 option meters)
1) Connect a normally-open contact closure switch between terminals 7 and 10
2) Set calibration lockout switch 3 ‘ON’
