Calibrating a Temperature Multiplexer

Scroll Prev Top Next More

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.
