Measuring the output voltages from the PX
MultiSensor Charger
A defective charger can damage the sensor causing its bad performance. We recommend
that you use one dedicated charger for each sensor.
The operation of the PX MultiSensor Charger can be verified by means of a standard
multimeter.
Procedure
1 Connect the charger to the AC mains power.
2 Use a multimeter to check the output voltage.
3 Verify the value you get is the same as the one shown on the products label (around
15 Vdc).

Investigating noise problems
When noise appears in the same frequency range as the sensors are using for their
communication, the resulting information may be unstable or unreadable.
Prerequisites
The TV80 has been set up with its hardware units connected as specified by the relevant
installation instructions.
Context
The TV80 offers a spectrum analyser that shows the signals from each hydrophone. The
graph in the
Spectrum
dialog box provides you with information about the background
noise and the signal strength in the selected frequency band. With this information you
can identify noise and find the "cleanest" frequencies. On the top and bottom parts of
the graph, the channel identifiers correspond to the relevant receiver channel. With the
channel identifiers you can easily see in which channels you have signals and noise.
The graph plots data using a 16 colour palette. Red colour corresponds to the maximum
value defined, while blue is the minimum.
• The upper scale (PI) identifies the channels for the PI Family receivers.
• The bottom scale (SR) identifies the channels for the SR Family receivers.
