8.10.1 Selection of the sampling rate
For better suppression of interferences, set the measuring rate and the line frequency as
follows:
Measuring rate Line frequency
100 Hz 50 Hz (parameter code 0)
120 Hz 60 Hz (parameter code 1)
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:
