5.3 Use of Phoenix Mobilis
CAUTION: WET AND DIRTY SURFACES
Risk of damage to the equipment. Avoid placing the instrument on wet or dirty
surfaces. Blocking of the probe will result in instrument failure.
CAUTION: BENDING OF THE PROBES
Risk of damage to the equipment. Do not bend the probes. The accuracy of the
Phoenix Mobilis will be affected.
Note:
Make sure that the ambient air is clean and free from any tracer gas when
the Phoenix Mobilis is switched on. Failure to do so will result in inaccurate
zero readings.
Do not touch the probe or brass sensor housing. Any changes in heat can
result in significant changes in signal causing false readings.
Switch on the Phoenix Mobilis with the power key.
While on the running screen, make sure that the sensitivity is set to the
'x100' range as this is the most sensitive. Adjust the sensitivity with the up
and down keys if required.
Hold the Phoenix Mobilis at 45
°
to the object under test and draw the probe
across the test area at a rate of approximately 25 mm per second. When a
leak is detected, the bar graph will fill, the reading will increase and the
frequency of the LED flasher will increase. The frequency of the audio
indicator will also increase if this function has been switched on in the main
menu.
