■
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.
■
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:
-
for the rms value (See in Ch.3)
-
MAX
for the maximum value
-
HOLD
to hold the value in memory
-
for display backlighting
