Safety Warnings and symbols used
The following safety warnings and precautions
must
be read and understood before
the instrument is used. They must be observed during use.
■
For safety, only connect the PAT to a supply that is properly earthed. If in doubt,
the supply should be checked by a qualifi ed electrician.
■
Do not use
the instrument if there are any signs of damage.
■
All test leads, probes and clips must be in good order, clean and with no broken or
cracked insulation.
■
Probes and clips should be held behind the fi nger guard.
■
Test leads not used during a measurement should be disconnected from the
appliance tester.
■
For dual voltage testers, both sockets can be live simultaneously.
■
Only connect one asset to the PAT during testing.
■
Tests should be carried out in the order recommended below. An appliance that
fails a test should be repaired before further testing is carried out.
Recommended Sequence:
1. Earth Bond/ Continuity of the protective earth conductor (Class I devices)
2. Insulation test (or earth leakage)
In addition further tests can be performed
3. Operation test
4. Leakage test
■
Only perform an operational test after the earth bond and insulation tests
have been completed, as this test operate at mains voltage.
■
During testing, ensure no hazard will exist as a result of normal running or
under fault conditions.
■
During testing the unit under test (asset) should not be touched, other than
using the appropriate accessories, as faulty appliances can present a shock
hazard.
■
Do not touch the exposed parts of test leads during tests as hazardous
voltages may be present due to potentially faulty appliance.
■
Do not touch the IEC extension lead socket pins especially during a test, as
hazardous voltages may be present due to a potentially faulty appliance
■
Assets should not be routinely Flash tested. Where fl ash testing is required,
refer to further guidance on Flash testing, section 4.5.
■
Replacement fuses must be of the correct rating and type. Refer to section 6.3
■
The USB connection should only be used by approved service personnel,
nothing should be connected to the USB port during testing.
■
Only use NiMH rechargeable 9V PP3 battery, do not use a non rechargeable type
Note: The PAT320 does not include the Flash test option.
Note: The PAT320 does not include the Flash test option.
as this could become dangerous if charged by the instrument.
■
Serviceable fuses should only be replaced with those that are suitably rated
■
In case of an emergency use an easily accessible power point

Battery function -
A 9 V PP3 rechargeable NiMH battery is fi tted to allow fast
restart should the PAT be unplugged and reconnected to an electrical supply in less
than 5 minutes.
Battery replacement
Warning:
■
Do not switch the instrument on with the battery cover removed
or test leads connected.
■
Only use NiMH rechargeable batteries.
1. Switch off the instrument and disconnect the instrument from any electrical
circuits.
2. Remove the battery cover.
3. Remove the old battery and refi t a new one, observing the terminal polarity.
4. Replace the cover and retaining screw.
Note: The PAT320 does not include the Flash test option.
All test leads, probes and clips must be in good order, clean and with no broken or
