GSafety Warnings
The following safety warnings and precautions must be read and understood before the
instrument is used. They must be observed during use.
nFor safety, only connect the PAT to a supply that is properly earthed. If in doubt, the
supply should be checked by a qualified electrician.
nDo not use the instrument if there are any signs of damage.
nAll test leads, probes and clips must be in good order, clean and with no broken or
cracked insulation.
nProbes and clips should be held behind the finger guard.
nTest leads not used during a measurement should be disconnected from the appliance
tester.
nFor dual voltage testers, both sockets can be live simultaneously.
nOnly connect one asset to the PAT during testing.
nTests 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. Visual inspection.
2. Earth bond/ continuity of the protective earth conductor (Class I devices).
3. Insulation test (or earth leakage).
In addition further tests can be performed, but ONLY AFTER 1 & 2 above.
4. Operation test.
5. Leakage test.
nOnly perform an operational test after the earth bond and insulation tests have been
completed, as this test operates at mains voltage.
nDuring testing, ensure no hazard will exist as a result of normal running or under fault
conditions.
nDuring testing the unit under test (asset) should not be touched, other than using the
appropriate accessories, as faulty appliances can present a shock hazard.
nDo not touch the exposed parts of test leads during tests as hazardous voltages may be
present due to potentially faulty appliance.
nDo not touch the IEC extension lead socket pins especially during a test, as hazardous
voltages may be present due to a potentially faulty appliance.
nAssets should not be routinely flash tested. Where flash testing is required, refer to
further guidance on flash testing in the user guide.
nReplacement fuses must be of the correct rating and type. Refer to the user guide.
nThe USB connection marked thus

should only be used by approved service
personnel; nothing should be connected to the USB port during testing.
nOnly use a NiMH rechargeable 8.4 V PP3 battery, do not use a non rechargeable type as
this could become dangerous if charged by the instrument.
nServiceable fuses should only be replaced with those that are suitably rated.
nIn case of an emergency use an easily accessible power point.
nOnly use Megger approved accessories with this product.
