Basic Leak Detection - Adixen Sensistor H2000-P PLUS Benutzerhandbuch

Basic leak detection

The Detection Mode is the default mode.
No numbers are shown on the display, and
the frequency is not an accurate measure of
the leak rate. Instead you hear a frequency
which increases as the probe approaches the
leak, and decreases as the probe is moved
away from the leak.
You will soon get used to listening for
changes in the frequency rather than to the
actual frequency. By moving the probe the
presence and accurate position of a leak will
easily be detected, even when there are other
leaks nearby.
Note!
• The tip of the hand probe gets warm when the
instru ment is in use. This is normal.
Important!
• Always connect the probe before switching on the
instrument.
• Never pull out the probe cable when the instrument
is in operation.
• Never put the probe in water or any other liquid.

In Detection Mode, keep moving the
probe to find out where the signal increases
and where it decreases. Let the audio signal
guide you to the exact position of the leak.
If you expose the probe to a constant gas
concentration you will hear the frequency
continue to increase slowly until it eventually
(30-45 seconds) levels off, and very slowly
declines again. The decline is the automatic
background adjustment coming into action.
The gas concentration being constant for
several minutes is being taken as an increased
background level.
