Calibrate the ControlLogix Analog I/O Modules Chapter 11
Calibrating the 1756-IT6I or 1756-IT6I2
This module only calibrates in millivolts. You can calibrate the module to
either a -12…+30 mV range or -12…+78 mV range, depending upon your
specific application.
While you are online, you must access the Module Properties dialog box.
See
page 207 in Chapter 10 for procedures.
Follow these steps to calibrate your module.
1. Connect your voltage calibrator to the module.
2. Go to the Configuration tab on the Module Properties dialog box.
3. At the Input Range, choose the range from the pull-down menu to
calibrate the channels.
4. Click OK.
IMPORTANT
The following examples show a 1756-IT6I module being
calibrated for a -12 mV…+78 mV range. The same procedures
apply for a 1756-IT6I2 module.
You also use the same steps to calibrate for a
-12 mV…+30 mV range.
