Earthed Appliance Test - F1
(For earthed appliances CLASS 1)
Please Note: A visual inspection test must be carried out before any others (refer to First Test Section)
The Earth Appliance Test completes the following sequences as part of its procedure:
1. Integrated Supply Mains Test
Refer to Integrated Test section
2. Integrated NCNT Test
Refer to Integrated Test section
3. Earth Bond Test (@200mA): 200mA test current, pass level less than 1Ω
4. Insulation Test (@ 250V or 500V): pass level greater than 1MΩ
Please Note: 250V insulation testing applies to Class 1 appliances if selected (refer to Technical Information for details to
change test voltage)
Procedure:
1. Complete a Visual Inspection on the DUI (Device Under Test). For details refer to the First Test section. If the DUT
passed the Visual Inspection, continue with the following instructions, if not, refer to the First Test section.
2. Plug DUT into DUT socket.
3. Connect earth clip to any exposed metal on the DUT.
4. Press the F1 key and wait for results (ensure that DUT's mains switch is on)
5. Read and record results appropriately
6. Unplug DUT
7. Press the enter key to return to the main menu
If the result was a pass - Tag the DUT with the appropriate tag including "next test due" date and "return to service".
If the result was a fail - Tag the DUT wit a danger tag and remove the DUT from service.
In some situations if the DUT is labelled with “Surge Protection Fitted” or if it is electronic and fails, conduct a 250V-insulation
test. Should it still fail, remove it from service. (refer to the Technical Information section to change test voltage).
Please Note: Ensure that the DUT to be tested is isolates from any ground loop.
Double Insulation Test - F2
(For double insulated appliances CLASS 2)
Please Note: A visual inspection test must be carried out before any others (refer to First Test Section)
The Double Insulation Test completes the following test sequences as part of its procedure
1. Integrated Supply Mains Test
Refer to Integrated Test section
2. Integrated NCNT Test
Refer to Integrated Test section
3. Double Insulation Test (@250V or 500V): pass level greater than 1MΩ
Procedure:
1. Complete a Visual Inspection on the DUI (Device Under Test). For details refer to the First Test section. If the DUT
passed the Visual Inspection, continue with the following instructions, if not, refer to the First Test section.
2. Plug DUT into DUT socket.
3. Connect earth clip to any exposed metal on the DUT (if any, or device can be wrapped in foil or use metal mesh braid,
Part No: TnT-ES 500)
4. Press the F2 key and wait for results (ensure that DUT's mains switch is on)
