DC 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.
To get the voltage in V, multiply the value read on the appropriate scale by the
reading coefficient shown in the table.

DECIBELS
Reminder: The measurement of an AC voltage can be expressed in decibels
(symbol dB). The decibel is the ratio of two quantities or level. Level N, in dB, of a
voltage U has the mathematical expression: N(dB) = 20 log
U
is the reference voltage of 0.775 V
