Recalibrating the Analog Input
Channels (Ch-A & Ch-B)
The analog input channels are calibrated at the
factory. If recalibration is needed, follow the flowchart
menu above and the instructions below.
1. Enter the ICAL menu to calibrate channel A
and channel B.
2. Select mA or Volt
3. Apply the low (4 mA or 0 V) and high (20 mA
or 10 V) signals as requested.
4. Press Enter to accept the values entered or
press Menu to exit calibration without saving
the changes.
Error Message (
Error
)
An error message indicates that the calibration or
scaling process was not successful. After the error
message is displayed, the scanner 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:
1. Input signal is not connected to the proper
terminals, or it is connected backwards.
2. Minimum input span requirements not
maintained.
