Chapter 8 Calibrate the ControlLogix Isolated Analog I/O Modules
Calibrate the Output Module You can calibrate the 1756-OF8I module for use with the following
output types:
• Current (mA)
• Voltage (V)
Calibrate the 1756-OF8I Module for a Current Output Type
When calibrating an output channel for use with a current output type, the Logix
Designer application commands the module to output specific levels of current.
You must measure the actual level and record the results to account for any
module inaccuracies.
Follow these steps to calibrate your module.
1. Connect your current meter to all module channels being calibrated.
2. Go online with your project.
3. Right-click the module you want to calibrate and choose Properties.
IMPORTANT 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.
