Power Up Checking
When the 3PL is turned on it will determine the type power source. This is either:
- 1 Phase 3 Wire
- 3 Phase 4 Wire (No Neutral wire)
- 3 Phase 5 Wire (With Neutral wire)
If the power source is 3 phase the tester will do an additional phase rotation test. The test will indicate that the phase rotation is correct or
incorrect. The 3PL will determine the power source by the plug attached to the mains power supply in 3PL front diagram.
3PL Cables
Single Phase Power Supply Cord: 3 Phase Power Supply Cord (4 and 5 pin types):
3 Phase Extension Lead Testing Cord:
Warning: Do not connect the 3 phase extension cable to a 3 phase wall outlet. Damage may result. This cable should only be
used for testing extension leads. Similar testing procedure are done with this cable as described in Ext Lead Test (refer to TnT).
Menu System
The menu system is divided into 3 menus. Menu 1 & 2 are related to single phase testing. Menu 3 is related to 3 phase testing.
When performing 1 phase test only the 1 phase DUT socket will be used. In menu 3 only the 3 phase DUT socket will be used.
The 3PL has an internal contactor that switches between the single and 3 phase outlet. You must select the correct type of test
to select the correct outlet. For example if a DUT is plugged into the single phase outlet and a 3 phase test is chosen then a
NCNT message will appear. This is because the 3PL has selected the 3 phase outlet and is not detecting any appliance.
Certain test will be available depending on what power source the 3PL is plugged into. The 3 different test modes are:
1 Phase 3 Wire: All tests except 3 Phase leakage test.
3 Phase 4 Wire: All test except single phase power test.
3 Phase 5 Wire:-All tests are available.
