AC Voltage, DC Voltage, and DC
Millivoltage Measurement
Note:
• If the range of the measured voltage is unknown
before measuring, select the maximum range
and then gradually reduce the measuring range
until the multimeter shows an accurate reading.
• The display will show “ ” if the reading is
over range (if there is an overload within the
selected voltage range). Select a higher range
to get a correct reading.
• In each range selection, the multimeter has an
input impedance of 10MΩ. This load effect can
cause measurement errors in high impedance
circuits. If the circuit impedance is less than or
equal to 10kΩ, the error can be ignored (0.1%
or less).
• Before using the multimeter, try measuring a
known voltage to verify it is working correctly.
WARNING
• To avoid electric shock, DC
measurement should be less than
1000Vrms, and AC measurement
should be less than 750Vrms. It is
possible to measure higher voltage,
but this may damage the multimeter
and cause personal injury.
• Always take extra care to avoid
electric shock when measuring high
voltages.
1. Turn the rotary dial to the AC voltage, DC
voltage, or DC mV (millivolts) position.

2. Insert the black test lead into the COM
terminal, and the red test lead into the
terminal.
3. Connect the test leads in parallel to the
object being measured. Hold them in place
until the reading on the display stabilizes.
