When you start to calibrate the probe with Insight, the probe enters calibration mode, and the compensation mode is automatically switched to Setpoint. In this compensation mode, you must enter the conditions of your calibration environment as temporary setpoint values in the Compensation setpoints tab of the calibration menu.
When you exit calibration mode, the values you have entered in the Compensation setpoints tab remain in use as the current setpoint values, but the compensation mode switches back to the selection that was in place before starting calibration (either Off, Setpoint, Measured, or External).
