Configuration Menu Structure of Configuration The device provides 2 parameter sets “A“ and “B“. By switching between the param- eter sets you can adapt the device to different measurement situations, for example. Parameter set “B“ only permits setting of process-related parameters. The configuration steps are assigned to different menu groups.
