Line Measurement is used for the manual control of line monitoring of the system. Manual line monitoring can be set on each channel of the amplifier.
When line monitoring is set to manual, this function will, based on zone selection, enable line measurement for at least 5 minutes. During this period, the line will be measured against previous calibrations.
To calibrate for the first time, the Activation parameter must be set to Start. This will initiate the process for the channels to be calibrated.
Typically, there will be an input on a rack device that should be enabled. Under such a measurement, all control outputs configured with Line Measurement will be toggled in the selected zones. For example, these can be used to turn off volume controllers.

Activation Start, Stop or Toggle the Line Measurement. It is recommended to use either Toggle or Start. The measurement will take 5 minutes.
Destination The zones in which Line Measurement will be activated. In such zones, all audio channels set to Manual will start to verify and report faults if any.
Priority The priority of the broadcast. Checking the Replace box will make this broadcast replace other broadcast with the same priority. If the box is not checked, the same priority will be shown as busy.
Enable Timeout This decides whether the function will timeout or not.
Timeout The amount of time in seconds that the Line Measurement will be active.
Example of Use
In one system there can be multiple Volume Controllers. These devices allow adjustments to the speaker line without accessing the complete system.
The volume controllers are active as long as they are supplied with a voltage, and they will stop working (go to volume override) if the voltage is removed.
When the volume controller is not supplied with a voltage the speaker line will have full volume.
For a zone, multiple volume controllers can be connected and they will be controlled by a control output on the amplifier.
These volume controllers will adjust the volume, and thereby the impedance of the channel which will appear as a fault.
With manual line measurements all volume controllers will be set to "volume override" when the line measurement is done.
This will ensure that the amplifier can read out the correct value of the line to deduce the state of it.
