Page 3: Operation Overview
Operation overview Your Socket & See tester has a special polarity test function. It is a little known fact that a system can be reverse wired with Live (Phase) to earth/neutral and earth/neutral to Live (Phase) The sockets will all work and conventional loop testers will show and test that everything is correct despite this very dangerous wiring condition. - Page 4 The DL 420 also has a No-trip test mode that is guaranteed not to trip a 30mA or higher rated RCD providing that the circuit is otherwise healthy.
- Page 5 Lead configuration for No-trip testing This is the default mode that the DL 420 will start in when turned on. This mode is most useful for testing either at socket outlets, luminaires, wiring terminals etc. in installations where the circuit under test may be protected by an RCD.
- Page 6 Test lead configuration Lead configuration for High Current 2-wire testing with TLI feature The TLI function is intended for use at distribution boards and similar points where you are measuring on the supply side of any Switch/RCD gear. The TLI measurement function is selected by pressing button 9 labeled ‘Ze/DB’.

Power ON/OFF - Pressing and releasing this button turns the DL 420 on - holding down for longer than two seconds turns the unit off (plus intelligent Auto Power Off is incorporated). When the DL 420 is first connected to a live socket it will automatically test the socket wiring to establish that the circuit wires have been connected to the correct terminals on the back of the socket.
- Page 10 The DL 420 will then automatically conduct a Loop test upon connection to the live supply and display the result. The supply voltage can be recalled by pressing the Voltage button.
