g. Apply power to the circuit being measured. The Instrument
will automatically indicate the correct polarity. The value of
the voltage being measured will be indicated on the numerical
display. The analog display will indicate the relative value and
can be used for nulling or peaking applications.
h. Remove all power from the circuit being measured and dis-
charge all capacitors prior to disconnecting test leads.
i. Open the circuit in which the current is to be measured and
securely connect the test leads in series. Ensure that the 460-4
is not connected across a voltage source which can exceed rat-
ings of the Instrument.
4.6 AC VOLTAGE MEASUREMENT:
a. Review safety precautions in paragraph 4.2.
b. Connect input test leads to the У-О and COMMON terminals.
c. Depress the ACV function switch.
d. Depress the appropriate voltage range switch as indicated in
