Calibrating the Meter (
Cal
)
To scale the meter without a signal source refer
to
The meter can be calibrated to display the process in
engineering units by applying the appropriate input
signal and following the calibration procedure.
The use of a calibrated signal source is strongly
recommended.
1. Press the
Up
arrow button to scroll to the
Calibration
menu (
CAL
) and press
Enter
.
2. The meter displays
Inpt1
. Apply a known
signal and press
Enter
.
The display will flash while accepting the
signal.
3. After the signal is accepted, the meter displays
dspl1
Press
Enter
.
Enter a corresponding display value for the
signal input, and press
Enter
to accept.
4. The meter displays
Inpt2
. Apply a known
signal and press
Enter
.
The display will flash while accepting the
signal.
5. After the signal is accepted, the meter displays
dspl2
. Press
Enter
.
Enter a corresponding display value for the

Enter
to accept.
After completing calibration the
save?
display will
need to be acknowledged using the Enter key before
calibration will take effect.
Minimum Input Span
The minimum input span is the minimum difference
between input 1 and input 2 signals required to
complete the calibration or scaling of the meter. The
minimum span is 0.10 mA.
If the minimum span is not maintained, the meter
reverts to input 2, allowing the appropriate input
signals to be applied.
Re-Calibrating the Internal
Calibration Reference (
ICaL
)
The
Internal Calibration
(
ICAL
) menu, located in the
Advanced
features menu, is used to recalibrate the
internal calibration reference. Recalibration is
recommended at least every twelve months. Refer to
for instructions.
Setting the Tag Display (

The meter can be set to display a combination of
seven alphanumeric characters for engineering units
(e.g.
GALLONS
) or for identification (e.g.
TANK
3
). Press

arrow to select next unit and
Up
arrow to
