RESISTANCE MEASUREMENT
Ω
Warning :
Before making a resistance measurement, make sure that the circuit is
cold and any capacitors have been discharged.
1.
Set the switch to
and press the
key. The
Ω
symbol is
displayed;
2.
Connect the black lead to the
COM
terminal and the red lead to «
+
»;
3.
Place the test probes or the crocodile clips on the terminals of the
circuit or component to be measured ;
The measured value is displayed on the screen

CURRENT MEASUREMENT (A)
The jaws are opened by pressing the trigger on the body of the device. The arrow
on the jaws of the clamp (see the diagram below) must point in the presumed
direction of flow of the current, from the generator to the load. Make sure that the
jaws have closed correctly.
Remark:
the measurement results are optimal when the conductor is centred in the
jaws (aligned with the centring marks).
The device automatically selects AC or DC according to which measured value is
larger. The AC or DC symbol blinks.
3.8.1
AC measurement
For an AC current measurement, proceed as follows:
1.
Set the switch to
and select AC by pressing the
key. The AC
symbol is displayed.
2.
Encircle only the conductor concerned with the clamp ;
