Scaling the Meter (
SCALE
)
The process inputs (4-20 mA and
10 VDC) can be scaled to display
the process variable in engineering units.
A signal source is not needed to scale the meter; simply program the
inputs and corresponding display values.
For instructions on how to program numeric values see
Setting Numeric Values
, page 22.
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:
5. Input signal is not connected to the proper terminals or it is
connected backwards.
6. Wrong signal selection in
Setup
menu.
7. Minimum input span requirements not maintained.
8. Input 1 signal inadvertently applied to calibrate input 2.
