Dc And Ac Voltages (V); Resistances (Ω); Continuity Sound Test ( ) - Chauvin Arnoux C.A 5205 Manual De Empleo

3 - DC AND AC VOLTAGES
I Connect the leads to the multimeter and connect it in parallel to the
circuit to be tested.
I Place the selector switch on the voltmeter function V. Automatic
selection of the range and the DC or AC mode; read the value measured.
I Memorise the value, if necessary, by pressing the HOLD button.
NB: On V AC, to benefit from HOLD, do not disconnect the leads.

Note: Because of its high input impedance, the instrument sweeps the ranges
when the leads are in the air.
4 - RESISTANCES
Never test a resistance on a live circuit
I Connect the leads to the multimeter and to the circuit or the
component to be tested.
I Place the selector switch on the ohmmeter function Ω
I Automatic range selection: read the measured value
I Memorise the value, if necessary, by pressing the HOLD button.
