CLEANING AND FAULT FINDING 22
Use a damp cloth for cleaning outside.
If internal chamber etc. requires disinfecting the following fluids may be used:
TERMINEX 2 (Available from Arrow Chemicals Ltd)
VIRKON (Available from Antec International)
These cleaning agents if used as instructed by the manufacturer should not be
harmful to this product, or accessories supplied for use with this product.
5. FAULT FINDING
5.1 General
Faults occurring during use can usually be traced to the titanium probe as this is
subject to high mechanical stresses. Possible faults are loss of effectiveness in
operation, a high-pitched screeching from the transducer unit and also a
wavering indication on the amplitude meter. The amplitude meter can be used
to monitor performance. Any fault condition will show as a loss of amplitude.
5.2 Fault conditions could be:
a) Probe insufficiently tightened.
b) Probe/Transducer faces not clean.
c) Probe too short.
d) Probe fatigued.
e) Transducer fault.
5.3 Loose Probe
A change in the pitch of the noise from the transducer (usually accompanied by
an indication on the amplitude meter) is a sure sign that the probe has worked
loose. Uncouple the probe from the transducer and clean both surfaces with a
soft cloth. Re-couple the probe to the transducer.
5.4 Fatigued Probe or Coupling Stud
Similar symptoms will be evident if the probe is fatigued, although this fault
would be detected at an earlier stage as there would have been difficulty in
obtaining satisfactory amplitude. However, to check that the fault is actually in
the probe, remove it and the coupling stud from the transducer and test the
probe's performance as described in section 2.6. If the probe is faulty, fit a new
one.
Again, symptoms common to a loose, or fatigued, probe may indicate a
fatigued stud. If necessary, renew it.
7.5 If your Soniprep has the door lock with a built in microswitch, ensure that the
door lock is fully turned in a clockwise direction. If the door lock is not fully
turned, it will not engage with the microswitch and your Soniprep will not
operate.
