Simpson 260 Series - DC Voltage Measurement: 0-1000 V Range

Operation
50V, and 250V ranges, read the figures directly. For the 500V
range, use the 0-50 figures and multiply by 10.
NOTE: Turn off power to the circuit and wait until the
meter indicates zero before disconnecting the
test leads.
4.9 DC VOLTAGE MEASUREMENT 0-1000V RANGE
WARNING
Be extermely careful when working with high voltage
circuits. Do not touch the Instrument or test leads while
power is on in the circuit being measured.
4.9.1 Before proceeding with the following steps, review the
Safety Precautions in Paragraph 4.2.
a. Set the function switch at + DC (Figure 4-1).
b. Set the range switch at 1000V (dual position with 500V).
c. Plug the black test lead into the - COMMON 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.
NOTE: Turn off power to the circuit and wait until the
meter indicates zero before disconnecting the
test leads.
