Probe options
In some applications the grey probe cover may restrict access to
the area under test, the grey probe cover can be removed by
pulling it off way from the instrument
is removed great care should be taken when using the instrument
and the following precautions noted:-
* Do not remove the semi-transparent probe sleeve, this
sleeve ensures the metal inner probe remains 1 mm
from the surface of the test area avoiding accidental dirt
and moisture ingress.
* Do not touch the probe and especially the brass sensor
housing. Heat from fingers can result in significant
changes in signal causing false readings.
* Avoid placing the probe on wet or dirty surfaces,
blockage of the probe will result in instrument failure.
Some applications may require a longer probe to gain access to
pneumatic joints and seems to be tested, the GasCheck Tesla is
also supplied with a 300mm probe that can be changed by the
user. To change probes carefully follow the following steps:-
* Switch the instrument OFF
* Remove the outer grey probe cover
* Place the box spanner (supplied with the instrument) over the existing probe so the spanner fits over the
,
brass nut
* Withdraw the spanner and probe assembly
To refit the short or the long probe follow the steps above but in reverse order.
CAUTION:
When using the box spanner to tighten the probe nut, ensure the nut is firmly tightened however do
not use additional tools as the tread may become damaged.
Should a probe become blocked, first remove the probe from the instrument. Then, use dry, clean compressed air to
blow out the blockage from the instrument end of the probe.
CAUTION:
The instrument has been factory calibrated using the standard short capillary which sets a certain flow
rate into the detector. The long capillary by nature of its construction has a different flow to improve the time
response in detection. This will change the calibration of the instrument when the long probe is used instead of
the short capillary. Thus the long probe is only to be used in finding leaks in difficult places where the standard
short probe cannot reach. The readings given by the long probe are only qualitative and the reading given by
the display is only to be taken as being relative to another value given by another leak site while using the long
probe.
WARNING:
Ensure safety guidelines are adhered to when using compressed air.
