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.
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.
Input Range
Input 1 & Input 2 Span
4-20 mA
0.15 mA
10 VDC
0.01 VDC
Calibrating the Meter with External Source (
Cal
)
Note: To scale the meter without a
signal source refer to Scaling the Meter,
page 35.
The controller 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.
