Why Am I Getting Error -200077 (0xFFFCF273) during thermocouple measurements when using the built in cold junction compensation (CJC) on the SCB-68, SCB-68A or SCXI-1102?

Solution: br/>You will need to properly configure your accessory in Measurement & Automation Explorer (MAX).

  1. Launch Measurement & Automation Explorer and navigate to the SCXI-1102 module
  2. Right-click SCXI-1102 and select Properties
  3. Select the Accessory tab
  4. Ensure that the Accessory in the drop down menu has CJC capabilities (such as the SCXI-1303)
  1. Launch Measurement & Automation Explorer and navigate to the DAQ device that is attached to the SCB-68
  2. Right-click on the DAQ device and select Configure
  3. Select the Accessory tab
  4. Ensure that under Accessory drop down box the SCB-68 is selected, then left-click the Configure button
  5. Under the CJC Configuration tab, ensure that the Temperature Reference Enabled checkbox is checked.
  6. Ensure that temperature reference sensor is enabled on the SCB-68. This can be found on page 6 of SCB 68 User Manual.
  7. Reading from AI0 or AI8 can also cause this error. These channels perform the CJC reading, and so they are not accessible for AI tasks.
