6-5 Measurement of resistance (Continuity check)
DANGER
¡
Do not apply voltage to the resistance range. Always test the circuit
or equipment to ensure it is surely de-energized before
measurement.
Zero Ω ADJ. function
This is a function to null the resistance of the test lead or fuse in order
to display the resistance of the equipment under test only.
Setting:
(1) Set the Range selector switch to theΩ(Continuity) position.
(2) Short the test leads: LINE (red) and EARTH (black).
(3) Press the Zero Ω ADJ. key with the Test button locked or with the
Remote control switch pressed. Then
mark is lit up and a
value of 0.00 Ω is displayed on the LCD. This value is saved in
the memory of the instrument and won't be cleared after turning
off the instrument.
