5.6.4 Using live measurements to tune the loop
To increase the stability of a loop system in the long term, it is recommended to do
take a view at the measurement values. This is only possible if the system is in the
status OK or BREAK.
1. Open the 'Peripherals and Supervision' page.
2. Click on 'Line Detection Statistics'.
Example 1: two separate loops in 'OK' state

This measurement is used to display the impedance and voltage drop in a loop
system. Because of voltage variability and phase shifting effects during the
measurement, it is possible that these values are a bit apart.
Speaker line 1 RMS 28 V
Impedance 79 ohms at 20 kHz
Speaker line 2 RMS 30 V
Impedance not relevant
● Voltage is above 25 V = very good
● A slight voltage increase can be measured, no impact on the functionality
● Impedance below 500 ohms = healthy loop system
Speaker line 3 RMS 32 V
Impedance 59 ohms at 20 kHz
Speaker line 4 RMS 29 V
Impedance not relevant
● Voltage is above 25 V = very good
● A slight voltage increase can be measured, no impact on the functionality
● Impedance below 500 ohms = healthy loop system
