NOTE 1 : If the contact symbol appears, the appliance needs to be switched ON.
NOTE: The PAT100 instruments perform various pre-checks prior to testing to ensure
the asset is not short-circuit and is switched on
NOTE 2: If the L-N or L-E symbol is flashing a low resistance has been detected. An L-E
fault will stop the test. See Measurement symbols table.
An L-N fault could damage the PAT tester and should be investigated.
To override an L-N warning, press the Class I button.
NOTE 3 : Faulty equipment may cause an RCD to trip during a Touch leakage test
