8. MEASUREMENT OF RESISTANCE
Set the switch to the W function :
auto selection of the 2 ranges.
Connect the red lead to the + terminal and the black to
the COM terminal then connect up to the element to be
measured.
Memorise the measurement, if necessary, by pressing
one of the HOLD keys.
Warning : never make resistance measurement on a
live circuit.
9. AUDIO CONTINUITY TEST
Set the switch to the
Connect the red lead to the + terminal and the black to
the COM terminal then connect up to the element to be
measured.
If the resistance is less than 40W the buzzer emits a
continous beep and displays the value of the resistance.
Warning : never make continuity test on a live circuit.
Set the switch to the
Press the MAX button
Connect the red lead to the + terminal and the black to
the COM terminal and connect up to the diode to be tested.
In the forward direction of the diode measured, the reading
is in V (calibre 4 V).
In reverse, the display indicates OL or voltage > 3.5 V.
It is therefore possible to test LEDs, in addition to stan-
dard diodes, or any other semi-conductor below the open
circuit voltage, on this function
Memorise the measurement, if necessary, by pressing
one of the HOLD keys.
Warning : never make diode test on a live circuit.
