MGCPlus - devices can perform auto calibration at adjustable intervals..
During this auto calibration, the amplifiers are balanced and the same is value is output for a period of time (up to several 100 ms).
When measuring signals that change slowly (e.g., a room temperature) the auto calibration does not cause any problems, but increases the accuracy, especially in the case of long measurements.
For quasi-static signals, auto calibration may remain activated.
An evaluation of signals that change quickly can be falsified if the measuring device always preaches a signal that does not change over a certain 100 ms.
For dynamic signals, auto calibration should be suppressed.
