TC Trim

 

The TC Trim Calibration Type will help to apply the correct Cold Junction to the thermocouple input without having the user perform math and determine a Target value. 

1. Select the TC Trim Calibration Type.

2. Select the correct input being calibrated in the Inputs field.

3. Sect the correct TC Type and Range (reference Table 1 for the corresponding ranges for each T/C type).

4. Source a temperature to that input.

5. Enter the sourced temperature into the Enter Target field.

6. Push the Calibrate button. A timer will count down from 30 seconds.

7. Once the Calibration Timer has counted down, the corresponding PV 1 or PV 2 value should match the sourced temperature.

Compare the sourced temperature with the corresponding PV 1 or PV 2 value.  Make further adjustments as-needed and perform additional calibrations.
