To switch the unit on or off press the ON/OFF button. Depending on the
intended use, connect the appropriate probe or the temperature sensor
to the SONAPHONE M (see Section:
Using the probes
).
A probe for structure-borne noise is used for locating leaks. The level of
ultrasound is besides the magnitude of the sound source also
dependent on the probe’s direction and distance from the sound source.
This effect can be used to locate and evaluate leaks. If no probe is
plugged into the unit, the message “No Probe” is displayed instead of
the ultrasound level.
