4 - DC AND AC VOLTAGES
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

NB: Accuracies given in the frequency reference range 35 to 500 Hz.
(1) Use possible from 20 Hz to 10 kHz with digital accuracy: 7.5% rdg ± 5 counts and analogue
accuracy: 7.5%. Additional error of 1% for a crest factor FC ≤ ≤ ≤ ≤ ≤ 3 and 3% for FC ≤ ≤ ≤ ≤ ≤ 5.
(2) Use possible from 20 Hz to 10 kHz with digital accuracy: 10% rdg ± 5 counts and analogue
accuracy: 7.5%.
