DC or AC Voltage Measurement
(see diagram 2)
Diagram 2
1.
Turn the rotary switch to the V or V position for voltage measurement.
2.
Insert the red test lead into the “V” terminal and the black test lead into the
“COM” terminal, Connect the test leads to the DUT being measured. The
measured value shows the true root mean square voltage (for stable inputs).
3.
For each range, the meter has an input impedance of 10MΩ. Input impedance
for V is about 4.5MΩ. This loading effect can cause measurement errors in
