Error Message (
Error
)
An error message indicates that the calibration or
scaling process was not successful.
After the error message is displayed, the meter
reverts to the input prior to the failure during
calibration or scaling and to input 1 during internal
calibration, allowing the appropriate input signal to be
applied or programmed.
The error message might be caused by any of the
following conditions:
1. Input signal is not connected to the proper
terminals or it is connected backwards*.
2. Wrong signal selection in
Setup
menu*.
3. Minimum input span requirements not
maintained.
4. Input 1 signal inadvertently applied to calibrate
input 2*.
*Not relevant when scaling the meter.
For instructions on how to program numeric values
see
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.

Calibrating the Meter with External
Source (
Cal
)
The meter can be calibrated to display the process
variable in engineering units by applying the
appropriate input signal and following the calibration
procedure.
The use of a calibrated signal source is strongly
recommended to calibrate the meter.
Warm up the meter for at least 15 minutes before
performing calibration to ensure specified
accuracy.
Time Base, Total Conversion Factor
& Total Reset
The time base, total conversion factor, and total reset
menus are located in the
Program
menu.
The total and grand total have their own independent
settings. This means that one can be displaying the
value in gallons while the other displays in million
gallons, liters, m
3
, etc.
Time Base
The time base is the amount of time over which the
rate parameter should accrue. For example, if the rate
was ten and the time base was in minutes, then the
total would increase by ten every one minute.
Total & Grand Total Conversion
Factor
The total & grand total conversion factor is the
amount by which the rate is multiplied before it is
added to the total or grand total. For Example, if the
rate was ten per second and the total conversion
factor was 100, the total would increase by 1000
every second. This is useful, for instance, if you want
to show rate in gallons and total in thousands of
gallons.
Total & Grand Total Reset
The totals can be programmed for automatic or
manual reset. In the automatic reset mode, a
programmable time delay is available to reset the total
or grand total after the assigned preset is reached.
The totals can also be reset via the front panel button,
via a switch across the on-board F4 terminal, the
PDA1044 digital I/O expansion module, or via a
Modbus command.
Non-Resettable Totalizer
The total and grand total can be password-protected
to prevent unauthorized resets. The grand total can
be programmed as a non-resettable total. See
Reset Password & Non-Resettable Total
on page
for details.
