Press and hold the ‘INSULATION’ key. The display will show the measured insulation
value for as long as the button is held depressed. If filter components are fitted to the
appliance being tested these may cause erroneous readings during the first few
seconds of the test. To ensure a valid reading allow a few seconds before noting the
displayed result.
NOTE: It is important to test the earth continuity in a Class I appliance prior to this test.
Otherwise, this test may not be valid.
d)
RUN
Full mains supply is applied to the appliance. The running current or the
earth leakage current, depending on the button pressed, can be measured
and displayed.
WARNING
This test can be hazardous if the earth continuity and insulation of the appliance have not been
checked prior to performing a run test. Always ensure that any appliance with electrically
energised moving parts is securely mounted before performing a test.
DO NOT TOUCH THE APPLIANCE DURING THE TEST.
DO NOT RUN THE APPLIANCE LONGER THAN NECESSARY.
DO NOT USE THE EASYPAT AS A MAINS POWER OUTLET.
Run current
Press and hold the ‘RUN AMPS’ key. The display will show the current drawn by the appliance
for as long as the button is held depressed.
Run Leakage Current
ENSURE THAT THE WANDER EARTH CLIP IS CONNECTED.
Press and hold the ‘RUN LEAKAGE’ key. The display will show the earth leakage current for
the appliance for as long as the button is held depressed.
WARNING
If the fuse in the EasyPat ruptures it must be replaced with a fuse as specified.
Fitting of any other type or rating of fuse is hazardous and may result in damage to the
EasyPAT.
e)
FLASH
NOTE: Due to the high voltages present during this test it should only be carried out by
suitable trained operators. Always inspect the flash probe for damage before use.
Flash voltage is applied:
i)
Along the mains lead phase/neutral and the earth for a Class I
instrument (test voltage 1.5kV).
ii)
Along the mains lead phase/neutral and the flash probe for Class II
instruments (test voltage 3kV).
iii)
Along the flash probe and the Wander earth clip for testing Class I
sub assemblies not connected to any mains plug (test voltage 1.5kV).
This test severely stresses the insulation of the appliance under test and
should not be carried out on a routine maintenance basis. Always check the
appliance manufacturers data to ensure that permanent damage will not be
done to the appliance if a flash test is carried out.
NOTE: With Class I appliances it is important to test the earth continuity prior to flash
testing otherwise the test may not be valid.
DO NOT TOUCH THE TEST APPLIANCE DURING TEST.
With Class II tests, the flash gun should be plugged into the safety test socket. The
flash gun is operated by pulling its trigger to expose its probe tip which should be
held firmly against any exposed metal surfaces on the appliance during the flash test.
Plug in the flash gun if required. The plug fits into the safety test socket.
With Class II tests the probe tip should be held firmly against any exposed
metal surfaces on the appliance for the duration of the flash test.
If there is not exposed metalwork on the appliance, metal foil should be
wrapped around the appliance and the Flash gun held in contact with the foil.
With sub assemblies attach the Wander earth clip to any metal which would
normally be connected to earth. Link together all connections which would
normally be connected to mains phase or neutral. Hold the probe tip firmly
against a mains connection for the duration of the test.
Press and hold the ‘FLASH’ key. The orange flash indicator will illuminate and
the flash leakage current will be measured and shown on the display for as long as
the key is held down.
