7. RESISTANCES
Never test a resistance on a live circuit.
Connect to the terminals of the circuit or the component to test.
If the «Voltest» light comes on, presence of a voltage U > 10 V . Unplug the
leads immediately and cut off the voltage before making the resistance measurement.
Analogue reading: to get the resistance in W, multiply the reading on the 50 scale
by the reading coefcient shown in the table.
Digital reading: if necessary, press the following keys, HOLD to hold in memory
and for display backlighting.

8. CONTINUITY SOUND TEST
Connection and specications: idem Resistances for 400 range.
Place the selector switch on the function.
Continuous audible beep emitted for a resistance R ≤ 400 .
9. DIODE TEST
Connection and specications: idem Resistances.
Place the selector switch on the function.
Analogue reading: voltage drop up to 2000 mV for the forward direction of the component.
50 scale, reading coefcient x 100
Digital reading: for the forward direction of the component, voltage drop up to
2000 mV.
Accuracy: digital 2 % rdg ± 2 counts and analogue 2.5 % full scale.
NB : The positive polarity is on the V Ω Hz terminal.
