Advanced Total and
Grand Total Programming
(
ADV TOTAL
&
ADV GTOTAL
)
The advanced total and grand total menu contain the
count (
COUNT
) and reset (
RESET
) menus. The count
menu allows the digit limit to be selected between
8-digit (bottom line only) and 13-digit (uses top and
bottom line to display full number) and the initial value
at which the total or grand total should start counting.
When using a 13-digit total or grand total, press the
function key assigned to display (default: F1) to view
the full amount once the value has exceeded
100,000,000 (decimal places are automatically trun-
cated). If a 13-digit total or grand total is displayed on
the bottom line and the value has exceeded eight dig-
its, the truncated value will flash to indicate that it is
not the complete value. To display 13-digit grand to-
tal, assigned the top and bottom line to grand total.
The reset menu is used to enable or disable the reset
of the total and grand total.
Non-Resettable Grand Total
The grand total reset may be permanently disabled by
selecting
YES
at the
PERMLOCK
menu after disabling
grand total reset.
Use caution
when selecting the
PERMLOCK
feature
as, once grand total reset has been permanently
locked, it cannot be unlocked.
Advanced Scaling and Calibration

SCALE.CAL
)
This menu offers options to scale or calibrate the meter.
Scaling the Input (

)
The scale menu in the
Advanced
menu is the same
as the scale menu in the
Input
) on page
for details about
scaling the meter.
Calibrating the Input (
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
CAL
menu should be used with a live signal coming
from a 4-20 mA transmitter connected to the process
being measured.
During calibration, the mA input value will be
displayed as
INP 1
and
INP 2
. Adjust the input
source until the desired mA value is shown. The use
of a calibrated signal source is strongly
recommended.
1. After accessing the
SCALE.CAL
menu, press the
Right-Arrow
button to scroll to the
Calibration
menu (
CAL RATE
) and press
Enter
.
2. Select the appropriate units for the desired
process variable, then press
Enter
. For
information on units, see Available Unit
Classes and Units on page
3. The meter displays
INP 1
. Apply a known
signal and press
Enter
. The display will flash
while accepting the signal.
4. After the signal is accepted, the meter displays
DSP 1
. Enter a corresponding display value
for the input signal , and press
Enter
to accept.
5. The meter displays
INP 2
. Apply a known
signal and press
Enter
. The display will flash
while accepting the signal.
6. After the signal is accepted, the meter displays
DSP 2
. Enter a corresponding display value
for the input signal and press
Enter
to accept.
7. After completing calibration, the
SAVE?
display
will need to be acknowledged using the
Enter
key before calibration will take effect.
