6-4 Voltage Measurement
1. Do not apply an input that exceeds the maximum rating of
each range.
2. Do not change over to other function or range during
measurement.
3. Measure in the maximum measuring range if you cannot
estimate a value to measure.
4. Do not hold the test pins on the leading end side from the
flanges on the test leads during measurement.
5. Be sure to perform measurement with parallel connection
to the load.
WARNING
6-4-1 DCV (DCV ) Maximum measurable voltage DC 1000 V
1) Objects of measurement
Voltages of batteries and DC circuits.
2) Measuring ranges (8 ranges) : 0.3/1.2/3/12/30/120/300/1000 V
3) Measurement procedure

Insert the red plug of
test leads in to the
+input terminal, and
the black plug into the
–COM terminal.
Turn the function/range
selector to the appropriate
range of DCV.
Turn on the power
switch (power ON:
Lamp blinks).
Turn the electrical zero adjuster (ZERO ADJ), to adjust the
pointer to the zero position at the left end of black DCV
•
A scales.
Apply the black test pin to the negative (–) potential side of
the circuit to be measured and the red test pin to the
positive (+) potential side (parallel connection to the load).
Read the indication on the DCV
•
A scales in a unit of V (volt).
Detach the test pins from the circuit to be measured.
Turn off the power switch (power OFF: Lamp blinking goes off).
Read the indication in the 1000 V range by multiplying 0 - 120
scales by 10. However, never measure voltages exceeding
1000 V to ensure safety.
It will be convenient to use the ±DCV function for circuits
where positive voltage and negative voltage are present.
