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
•
always contact the touch pad around the test button
When a high voltage is measured between two wires,  shows on the display:
•
If the PE wire is live and you contact the touch pad, the W above the touch
pad 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 more information, see the RCD Tripping Time table in
the Specifications section of this manual.
