Simpson 260 Series - DC Voltage Measurement: 0-500 V Ranges

Operation
c. Set the range switch at ТУ (COMMON position with 2.5 V).
d. Connect the black test lead to the negative side of the circuit
being measured and the red test lead to the positive side of
the circuit.
e. Read the voltage on the black scale marked DC and use the
figures marked 0-10. Then divide the reading by 10.
NOTE: For polarity reversing see paragraph 4.3.
4.8 DC VOLTAGE MEASUREMENT 0-2.5
THROUGH 0-500V RANGE
a. Set the function switch at + DC (Figure 4-1).
b. Plug the black test lead into the — COMMON jack and the red
test lead into the 4- jack.
c. Set the range switch at one of the five voltage range positions
marked 2.5V, 10V, 50V, 250V or 500V.
NOTE: When in doubt as to the voltage present, always
use the highest voltage range as a protection to
the Instrument. If the voltage is within a lower
range, the switch may be set for the lower range
to obtain a more accurate reading. Be sure pow-
er is off in the circuit being measured and all
capacitors discharged.
d. Connect the black test lead to the negative side of the circuit
being measured and the red test lead to the positive side of the
circuit.
e. Turn on the power in the circuit being measured.
f. Read the voltage on the black scale marked DC. For the 2.5V
range, use the 0-250 figures and divide by 100. For the 10V,
