X.2 Safety Warnings
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 qualified 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 finger 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, but ONLY AFTER 1 & 2 above
3. Operation test
4. Leakage test
! Only perform an operational test after the earth bond and insulation tests have been completed, as this
test operates 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
