Interference frequency suppression

The frequency of your AC power system can interfere with the measured value, particularly
when measuring in low voltage ranges and using thermocouple elements. You can enter the
mains frequency for your system here (50 Hz or 60 Hz).
The interference frequency suppression parameter applies to all analog electronic modules.
With this parameter, you also specify the integration and conversion time of the various
modules. See the technical data for the analog electronic modules.
11.3.5 Reference junction slot
This parameter allows you to assign a slot (none, 2 to 13) where the channel for measuring
the reference temperature is located (calculation of the compensation value).

11.3.6 Reference junction input
This parameter allows you to set the channel (0/1) for measuring the reference temperature
(calculation of the compensation value) for the assigned slot.
