The gas selection allows the correct calibration curve for the gas to
be detected to be selected. See
Table: Smallest detectable leak
level
for a list of gases available. Select the required format with
the up or down key to move the tick to the desired position and
then press the esc key to return to the main menu.
5.5 Probe options
CAUTION: SEMI TRANSPARENT PROBE SLEEVE
Risk of damage to the equipment damage. Do not remove the semi transparent
probe sleeve, this makes the inner metal probe remains 1 mm from any surface in
order to prevent any accidental dirt and moisture ingress.
CAUTION: OVER TIGHTENING
Risk of damage to the equipment damage. Only use the box spanner supplied with
the Phoenix Mobilis to tighten the probes. Other tools may result in over tightening of
the nut and permanent damage to the instrument.
In some circumstances, the grey probe cover may restrict access to the
area to be leak tested. Remove the probe cover by pulling firmly with one
hand to reveal the short probe, see
Figure: Remove the probe cover
.
Some applications may require a longer probe in order to reach inaccessible
areas. The Phoenix Mobilis is supplied with a 300 mm long probe in the
storage case.
For probe installation see the procedure that follows:
1.
Make sure that the instrument is switched off. Remove the probe cover
to access the short probe as shown in
Figure: Remove the probe
cover
.
2.
Slide the box spanner over the short probe as shown in
Figure:
Change between short and long probes
.
3.
Unscrew the probe counterclockwise.
4.
Remove the spanner and the probe assembly. To replace the short
probe with the long probe, perform the same sequence in reverse
order.
Note:
When detecting leaks with the long probe installed, the response time
of the Phoenix Mobilis is significantly increased. The speed at which
the probe is drawn over the inspection surface should be reduced to
around 10 mm per second.
