Chapter 8 Calibrate the ControlLogix Analog I/O Modules
The Group High Reference Results dialog box indicates the status of each
channel after calibrating for a high reference.
14. If channels are OK, click Next.
If any channel reports an error, return to step 12
and click Retry until the
status is OK.
If the error persists indefinitely, click Stop to exit calibration. The channel
remains calibrated to the accuracy level achieved at factory calibration.
15. When the Calibration Completed dialog box appears, click Finish.
Calibrate the Output Module
You can calibrate the 1756-OF8I module for use with the following
output types:
• Current (mA)
• Voltag e ( V )
This section shows how to calibrate the 1756-OF8I modules for use with only
current outputs.
The calibration process is generally the same if you calibrate the module for use
with voltage inputs except for the following differences:
• You connect a voltage meter to the module.
• The low reference signal measured at the module is in volts.
• The high reference signal measured at the module is in volts.
