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

d. Turn off power to the circuit to be measured and discharge
Operation
any capacitors.
e. Connect the test leads across the circuit voltage to be measured
with the black lead to the grounded side.
f. For the 02.5V range read the value directly on the scale
marked 2.5 VAC. For the 10V, 50V, and 250V ranges, read
the red scale marked AC and use the black figure immediately
above the scale. For the 500V range, read the red scale marked
AC and use the 0-50 figures. Multiply the reading by 10.

4.11.1 Before proceeding with the following steps, review the
AC VOLTAGE MEASUREMENT 0-1000V RANGE
Be extremely careful when working in high voltage
circuits. Do not handle the Instrument or test leads
while the circuit being measured is energized. OB-
SERVE ALL SAFETY PRECAUTIONS in paragraph 4.2
and in the instruction manual for the equipment being
tested.
Do not attempt any voltage measurement which may
exceed 1000 volts or the circuit-to-ground voltage of
the Instrument, 1000 volts maximum.
Be sure that the range switch is set to the 500V/1000V
range, function switch to AC position, and test leads
connected to common and 1000V jack.
Do not touch the Instrument or test leads while the
power is on in the circuit being measured.
Be extremely careful when working in high voltage
circuits.
Safety Precautions in Paragraph 4.2.
a. Set the function switch at AC (Figure 4-3).
b. Set the range switch at 500/1000V position.
