4.10 DC Voltage Measurement 0-1000V Range
!
Be extremely careful when working with high voltage circuits. Do not
touch the Instrument or test leads while power is on in the circuit being
measured.
Before proceeding with the following steps, review the Safety Precautions in 4.2.
a. Set the function switch at +DC (Figure 4-
1).
b. Set the range switch at the 250V/500V/
1000V position.
c. Plug the black test lead into the – COM-
MON jack and the red test lead into the
1000V jack.
d. Be sure power is off in the circuit being
measured and all capacitors discharged.
Connect the black test lead to the nega-
tive side of the circuit being measured
and the red test lead to the positive side
of the circuit.
e. Turn on power in circuit being measured.
f. Read the voltage using the 0-10 figures
on the black scale marked DC. Multiply
the reading by 100.
