COLD JUNCTION CALIBRATION
The ambient temperature at which this calibration should be performed is 15 to
35 °C (59 to 95 °F). A Temperature indicator with 0.1 °C resolution and
accuracy is required to perform this calibration.
1. Enter Programming Menu, and verify the following:
2. Connect a thermocouple probe of known accuracy and type (J, K, E, T, or N)
3. Connect a reference temperature probe to measuring end of the CUB4TC
4. Compare the unit display with reference temperature indicator (or calibration
