Selection of the sampling rate

For better suppression of interferences, set the measuring rate and the line frequency as
follows:
Measuring rate
100 Hz
120 Hz
Interferences can be caused by the power supply grid.
For fast measurements, you can select a measuring rate of 600 Hz (parameter code 2) as of
firmware V1.2.0.
The setting has an effect on the frequency response of the signal path.
The following diagrams show the frequency response:
