„ Connect the leads to the multimeter and connect in parallel to the circuit to be
tested.
„ When the order of magnitude is not known, place the switch on the highest range
then progressively lower to the appropriate range.
For the 1000 V rating:
„ Analogue reading: to get the voltage in V, multiply the value read on the appropriate
scale by the reading coefficient shown in the table.
„ Digital reading: if necessary, press the following keys:
