This section outlines a few practical setups to make tests faster and more efficient.
How to Test a Mains Socket and Ring Installation
The mains socket test checks that the mains voltage is present, the frequency is 50 Hz/60 Hz,
and the wiring of the mains socket is correct.
For a valid socket test:
connect all test leads (phase, neutral, and protective earth) to the mains socket
the mains line cord provides a quick connection to the socket
When a high voltage is measured between two wires, Y shows on the display:
If the PE wire is live, the W is lit, the PE annunciator in the display is lit, and the beeper
sounds.
If the L and N terminals are reversed, the Tester shows an arrow above the terminal
indicator symbol. The Tester automatically reverses these internally and allows the test.
When configured for UK operation, the Tester inhibits the test.
If the L and PE terminals are reversed, the Tester shows an arrow below the terminal
indicator symbol and inhibits the test.
If the N, PE, or installation wire is open or broken, the Tester shows the terminal as a
crossed circle. The test can start if the wire is not required for this test.
If the trip time meets the appropriate standard of the RCD, the RCD indicator shows. For
