Operating Instructions
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC,
are very dangerous and should be measured with great care.
1. ALWAYS turn the function switch to the OFF position when the meter is
not in use
2. If "OL" appears in the display during a measurement, the value exceeds
the range you have selected. Change to a higher range
DC Voltage Measurement
CAUTION: Do not measure DC voltages if a motor on the circuit is
being switched ON or OFF. Large voltage surges may occur that can
damage the meter.
1. Set the function switch to the green VDC position
2. Insert the black test lead banana plug into the negative COM jack
Insert the red test lead banana plug into the positive V jack
3. Touch the black test probe tip to the negative side of the circuit
Touch the red test probe tip to the positive side of the circuit
4. Read the voltage in the display
AC Voltage (Frequency, Duty Cycle) Measurement
WARNING: Risk of Electrocution. The probe tips may not be long
enough to contact the live parts inside some 240V outlets for
appliances because the contacts are recessed deep in the outlets.
As a result, the reading may show 0 volts when the outlet actually has
voltage on it. Make sure the probe tips are touching the metal contacts
inside the outlet before assuming that no voltage is present.
CAUTION: Do not measure AC voltages if a motor on the circuit is
being switched ON or OFF. Large voltage surges may occur that can
damage the meter.
