For convenience reasons, a separate parameter set is created with one multiplexer time slot which is set to the operating range to be calibrated. The sample rate is set to 200 ms (to obtain a very smooth signal averaging). Then, the multiplexed voltage input (and its first sub-channel) must be defined as described as before. And a display output for the multiplexed voltage input should be defined as well. Then, call menu item Hardware → Calibrate device... and select the nonlinearized temperature signal, attach the voltage for the linearized temperature (e. g. with a thermocouple calibrator) and press the corresponding button of the two-point calibration. Attach the other linearized temperature and press the corresponding button of the two-point calibration. Then press OK. The device is now calibrated.
