6–8 Calibrating Your Module
Publication 1794-6.5.7 – April 1997
The following procedure assumes that you are using
DeviceNetManager software (cat. no. 1787-MGR) and have the
thermocouple/mV module installed in a working system.
Offset Calibration
Inputs can be calibrated one at a time or all at once. To calibrate the
offsets for all inputs at once, proceed as follows:
1. Connect 0.000V across each input channel. Connect all high
signal terminals together and attach to the positive lead from the
precision voltage source. Connect all low signal terminals
together and attach to the negative lead.
2. Apply power to the module for 45 minutes before calibrating.
3. Click on Configure for the slot containing the thermocouple
module.
