Calibrate Your Modules Chapter 5
Calibrate the RTD Module
The 1732E-IR4IM12R does not calibrate for voltage or current. It uses two
precision resistors to calibrate the channels in ohms. The module has a preset
calibration points for the sensor type configured for each input channel,
Perform the calibration process through the RSLogix 5000 software.
While you are online, you must access the Calibration tab on the Module
Properties dialog box. See Edit Your Module Configuration
on page 21.
1. Click Calibration Tab on the Module Properties dialog box.
2. Check the Calibrate checkbox to specify which channel to calibrate.
In this example, check Channels 0…3.
3. Under Calibrate Channels select One At a Time.
4. Click Start Calibration, which is active when:
• the system is online, and
• you selected at least one of the channels.
