Simpson 260 Series - DC Voltage Measurement: 0-1 V Range

Operation
Prior to making voltage measurements, review the
SAFETY PRECAUTIONS listed in paragraph 4.2. Also,
when using the 260 as a millivoltmeter, care must be
taken to prevent damage to the indicating instrument
from excessive voltage. Before using the 250 millivolt
range, use the 1.0-volt DC range to determine that the
voltage measured is not greater than 250 millivolts (or
.25 volt DC).
a. Set the function switch at + DC (Figure 4-1).
b. Plug the black test lead in the — COMMON jack and the red
test lead into the +50 ,AMPS/250mV jack.
с. Set the range switch at 50 „АМР$ (COMMON) position with
50V.
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 0-250. Read directly in millivolts.
NOTE: For polarity reversing see paragraph 4.3.
4.7 DC VOLTAGE MEASUREMENT 0-1V RANGE
a. Set the function switch at + DC (Figure 4-1).
