5.5.2.2 Impedance measurement
● Nominal Impedance is the estimated impedance value of the line in ohms.
● The tolerance is the maximal deviation of the nominal impedance in %.

1. Enable the 'En' flag for each zone you want to monitor.
2. Under 'Pilot RMS', set the 'Value' and 'Tolerance' to a value of between 5…15.
– 'Value' = 17 and 'Tolerance' = 6 provide a good starting point.
– If optimization is required, increase the values.
3. Set 'Impedance' under 'Type'.
