Calibration Procedure

This example describes how to calibrate a channel on the 5034-IRT4I module for use with the RTD input type. The 5034-IRT4I module uses the following resistors to calibrate in ohms:
  • 1 Ω resistor for low reference calibration
  • 448 Ω resistor for high reference calibration
Apply Low and High Signal references to the analog input module to calibrate it. The references must match the input range the channel is using.

  1. Connect the low reference resistor to the channel being calibrated.
  2. Go online with the project and make sure that the controller is in Program Mode.
  3. Confirm that the channel to be calibrated is configured for the correct Input Range.
  4. On the Calibration view in the Module Properties dialog, select Start Calibration.
  5. When the dialog appears to confirm that you want to calibrate the channel, select OK.
  6. Select the channels one at a time or in groups to calibrate and then select Next.
  7. When the Attach Low Reference dialog appears, connect a 1 Ω resistor to the channel being calibrated.
  8. Select Next.
    The Low Reference Results dialog appears and indicates the status of the calibrated channel.
  9. If the Status is OK, select Next.
    If the Status is not OK, repeat the calibration procedure.
  10. When the Attach High Reference dialog appears, connect a 448 Ω resistor to the channel being calibrated.
  11. Select Next.
    The High Reference Results dialog appears and indicates the status of the calibrated channel.
  12. If the Status is OK, select Next.
    If the Status is not OK, repeat the calibration procedure.
  13. When the Calibration Completed dialog appears, select Finish.
