1. Turn the left-hand rotary knob to the Voltage position (V).
 The display illuminates and has a black background.
2. For a two-wire test, plug your test-leads into the green and
red sockets as indicated in the INFO bar.
2.1. For a three-wire test or if you are using a mains plug
lead, plug the green protective earth (PE) test-lead
into the green socket, red live (L) test-lead into the
red socket, the blue neutral (N) test-lead into the blue
socket.
3. Connect the green (PE) test-lead, to the Earth conductor, the red (L) test-lead to the Live conductor and the
blue test-lead to the neutral conductor of the circuit to be measured.
You do not need to press the test button.
The test is running continuously and is constantly displaying the voltages on the test terminals.
4. For two-wire tests, the instrument displays a single voltage.
4.1. For three-wire tests, the live-to-PE, live-to-neutral and
