Instruction manual

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).

Ext Lead Test - F3

(For extension lead/power board & IEC lead)

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

The Ext. 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:

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 in IEC adaptor lead into IEC socket (remove earth lead if inserted - please read note below).

3. Plug male end of extension lead or power board in to TnT tester DUT socket.

4. Plug IEC adaptor lead into extension lead/power board socket.

5. Press the F3 key and wait for results

6. Read and record results appropriately

7. Unplug extension lead/power board

8. 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.

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.
