Class 1 - Earthed Appliance Test - F1

Please Note: A Visual Inspection test must be carried out before any others (refer to First Test Section)

The Class 1- 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)

In some situations if the DUT is labelled with “Surge Protection Fitted” or if it contains MOV’s (Metal Oxide Varistors), conduct a 250V-insulation test.

*If unsure refer to the AS3760 Standard.

Should it still fail, remove it from service. (Refer to the Technical Information section to change test voltage).

Procedure:

Complete a Visual Inspection. Only proceed if test passed.
Plug device into appliance socket.
Connect earth clip to any exposed metal on the device.
Press the F1 key and wait for results (ensure that device is powered on)
Read and record results appropriately
Unplug device
Tester will return to Main menu A automatically

If the result was a pass - Tag with PASS tag showing "next test due" date and return the device to service.

If the result was a fail - Tag the DUT with a DANGER tag and remove the device from service.

Please Note: Ensure that the device is isolated from any ground loop.

Class 2 Test - Double Insulation Test - F2

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:

Complete a Visual Inspection ( Note: Only proceed if test passed !! )
Plug the appliance into appliance test socket.
Connect earth clip to any exposed metal on the device (if any, or device can be wrapped in foil or use metal mesh braid, Part No: WCM-ES 500)
Press the F2 key and wait for results (ensure the device is powered on)
Read and record results appropriately
Unplug device
Tester will return to Main menu A automatically

If the result was a pass - Tag with PASS tag showing "next test due" date and return the device to service.

If the result was a fail - Tag with a DANGER tag and remove the device from service.

In some situations if the device is labelled with “Surge Protection Fitted” or if it contains MOV’s (Metal Oxide Varistors), conduct a 250V-insulation test. (Hint always read the compliance plates during Visual)

*If unsure refer to the AS3760 Standard.

Should it still fail, remove it from service. (Refer to the Technical Information section to change test voltage).

Lead Test (Ext Lead Test) - F3

Please Note: A Visual Inspection test must be carried out before any others (refer to First Test Section)

The Lead TEST completes the following sequence as part of its comprehensive testing procedure:
1. Integrated Supply Mains Test	Refer to Integrated Test section
2. Earth Bond Test (@ 200mA): 200mA test current, pass level less than 1Ω
3. Insulation Test (@ 250V or 500V): pass level greater than 1MΩ
4. Continuity and Polarity Test 240VAC @ 2mA Checks continuity & polarity of leads

Procedure:

Complete a Visual Inspection. Only proceed if test passed.
Plug in supplied orange IEC adaptor lead supplied into front IEC socket.
Plug male end of extension lead or power board in to TnT – Series appliance socket.
Press the F3 key and wait for results.
Read and record results appropriately.
Unplug extension lead/power board.
Tester will return to Main menu A automatically.

If the result was a pass - Tag with PASS tag showing "next test due" date and return the device to service.

If the result was a fail - Tag with a DANGER tag and remove the device from service.

Please Note:

Extension leads should always be uncoiled before using or testing.
Please ensure that the IEC Adaptor & the IEC socket are inserted firmly or it may result in a continuity/polarity fail.
