If there is a fault with the mains power connection, you may see one (or more) of the Indicator LEDs turn
red. This may indicate a serious issue with the mains power supply - consult a qualified professional before
proceeding. This won’t apply when using battery power.
Standard Mains Supply Test result with no issues.
N-E Fault - If the N-E light in on, DO NOT PROCEED. The N-E LED will turn red if there
is a voltage difference between the neutral and earth, or if no earth is connected.
If you are working from a generator or inverter this is likely to occur and you may
need to consult a qualified electrician before proceeding.
If the N-E LED is red, and A-N is green, there is a fault with the Mains Supply
You may also see more than one, or all of these turn red. For more information, see Mains Supply Test (Page 26)

If you are using your TnP Prime with the WinPATS App, you do not need to operate the TnP Prime manually - all
functions can be controlled directly from the App.
Class 1 - Earthed Appliance Test - Menu A - F1
The Class 1 Test completes the following sequences as part of its procedure:
• Integrated Supply Mains Test - Refer to Integrated Test section
• Integrated NCNT Test - Refer to Integrated Test section
• Earth Bond Test (@ 200mA): 200mA test current, pass level less than 1Ω
• Insulation Test (@ 250V or 500V): pass level greater than 1MΩ
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 AS/NZS:3760 Standard. Should it still fail,
remove it from service. (Refer to the Technical Information section to change test voltage).
Note: Ensure that the device is isolated from any ground loop.
Procedure:
1. Complete a Visual Inspection.
2. Plug device into appliance test socket.
3. Plug the IEC Clamp Cable into the IEC socket of the TnP Prime
4. Connect earth clip to any exposed metal on the device. If this is not possible, you can use a metal mesh
braid to establish an earth connection (sold separately)
5. Navigate to Main Menu A, then Press the F1 key to begin the test
6. The test will be conducted
7. Once complete, read and record results appropriately
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.
