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 input 2 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.
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
To scale the meter without a signal source,
refer to
Scaling the Meter without a Signal
, page
Warm up the meter for at least 15 minutes
before performing calibration to ensure
specified accuracy.
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.
