Operating Instructions
7. Turn off the power in the circuit which is being mea-
sured before disconnecting meter leads.
D.C. VOLTAGE MEASUREMENTS, 5000 VOLT RANGE
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 D. 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 D.C. 5000 V. jack.
4. Be sure power is off in the circuit to be measured and
all capacitors have been discharged; connect the black
test lead to the negative side of the circuit to be mea-
sured and the red test lead to the positive side of the
circuit.
5. Turn on the power in the circuit. Do not touch the
meter or test leads. If the pointer deflects to the left
side of zero, the anticipated polarity is opposite the
actual circuit polarity. Turn off the power in the circuit
being tested. Set the function switch at —D.C., and
turn on the power again. This will correct the polarity
as it is applied to the meter.
6. Read the voltage using the 0— 50 figures on the black
arc which is second from the top of the scale. Multiply
the reading by 100.
7. Turn off the power before disconnecting the test leads.
