Set-Up Receiver Unit
1.
Connect the antenna. The magnetic vehicle mount antenna is highly recommended if operation is inside a vehicle.
2.
Switch the receiver unit on with a short press on the button
.
4.5
Radio Range
At manufacture every system is tested over a distance of 100 metres, line
-of-sight on ‘low power’ mode and with the
portable receiver antenna. Radio range will be considerably increased in the ‘high power’ mode.
4.6
Inter
-Transducer Distance
An accurate inter
-transducer
distance is necessary to achieve accurate leak pinpointing.
The accuracy of the correlation
result will only be as good as the accuracy of the distance measurement.
When making distance measurements, it is the actual pipe length that must be measured; be aware that water mains do not
always run in a straight line or at a uniform depth.
4.7
Velocity
An accurate sound velocity is necessary to obtain accurate leak location from the correlation result. In most cases the sound
velocity that is automatically used when entering the pipe diameter and material will be adequate.
However, it is always
highly recommended to check and correct the sound velocity in the pipe to reduce leak position error. T
he method of
velocity correction is described in Section
5.7.
4.8
Filter Settings
The default filter settings will give good results most of the time.
Sometimes with difficult leaks adjusting the filters will
obtain a more definitive result.
Adjustment of the filters and the use of the coherence display are explained in
section
5.9.
