WARNING
● If the above sequence is NOT displayed or the RED LED is on for
any reason , DO NOT PROCEED AS THERE IS INCORRECT
WIRING. The cause of the fault must be investigated and rectified.
● THE WIRING CHECK LED (P-E, P-N) of this instrument is to
protect the user from electrical shock resulting from incorrect
connection of Line and Neutral or Line and Earth.
When the Neutral and Earth conductors are incorrectly wired, the
WIRING CHECK LED function cannot identify the incorrect
connection. Other procedures and test must be conducted to
check and confirm that the wiring is correct prior to making
measurement.
Do not use this instrument to check the correct wiring of the
power supply. Kyoritsu will not be held liable for any accident that
may result from incorrect wiring of the power supply line.
(3) Voltage Measurement
When the instrument is first connected to the system, it will display the
phase-neutral voltage which is updated every 1s. This mode is cancelled
whenever the test button is pressed. If this voltage is not normal or as
expected, DO NOT PROCEED.

5.2 Measurement of the Loop Impedance
(1) Set the instrument to the 200Ω or 2000Ω range.
If the instrument is set to the 20Ω range slight sparking may occur
when testing with the distribution board lead although the unit has
been designed to minimize this.
(2) Connect the lead to the instrument.
(3) Plug the moulded mains plug to the socket being tested.
(4) Check the LED's are lit as indicated in section 5.1. If not DO NOT
PROCEED - check wiring.
(5) Note the mains voltage if required.
