Understanding the Rotary Switch
Select a primary measurement function by positioning the rotary switch to one of the
icons around its perimeter. For each function, the meter presents a standard
display for that function (range, measurement units, and modifiers). Button choices made
in one function do not carry over into another function.

DMM Measurement and Setup
DC Voltage Measurements
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.
• Set the function switch to the VDC position.
• Insert the black test lead banana plug into the negative COM jack. Insert the red test
lead banana plug into the positive V jack.
• Read the voltage in the display.
AC+DC Voltage Measurements
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.
• Set the function switch to the VDC position.
• Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive V jack.
• Press the
MODE
key to switch the V AC+DC Voltage functions.
• Read the AC+DC voltage in the display.
AC Voltage Measurements
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.
