Operating Instructions
For the 10 V., 50 V., and 250 V. ranges, read the red
arc marked A.C., and use the red figures directly
below the arc.
For the 1000 V. range, read the red arc marked A.C.;
use the 0 — 10 figures and multiply by 100.
MEASURING A.C. VOLTAGE TO 5000 VOLTS
WARNING
Be extremely careful when working in high voltage
circuits. Do not touch the meter or test leads while
power is on in the circuit being measured.
1. Set the function switch at A.C.
. Set the range selector switch at 5000 V.
3. Connect the black test lead into the COMMON - jack
and the red test lead into the A.C. 5000 V. jack.
. Be sure the power is off in the circuit to be measured
and that all its capacitors have been discharged. Con-
nect the test leads into the circuit.
5. Turn on the power in the circuit to be measured. Do not
touch the meter or test leads. n
6. Read the voltage on the red arc marked A.C.; use the
0— 50 figures and multiply by 100.
7. Turn off the power before disconnecting the test leads.
MEASURING OUTPUT VOLTAGES
An output voltage is the A.C. component only, when there
is a mixture of A.C. and D.C. voltages. This occurs mostly
in amplifier circuits.
