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.
1. Set the function switch to the position.
2. Insert the black test lead banana plug into the negative
COM
jack and
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 and the
red test probe tip to the positive side of the circuit.
4. Read the voltage in the display. The display will indicate the proper
decimal point and value. If the polarity is reversed, the display will show
(-) minus before the value.
5. Reset the function switch to successively lower positions to obtain a
higher resolution reading.
DC Current Measurements
CAUTION:
Do not make current measurements on the 20A scale for longer
than 30 seconds. Exceeding 30 seconds may cause damage to the meter
and/or the test leads.
1. Insert the black test lead banana plug into the negative
COM
jack.
2. For current measurements up to 200mA DC, set the function switch to
the highest DC mA position and insert the red test lead banana plug
into the (mA) jack.
3. For current measurements up to 20A DC, set the function switch to the
20A range and insert the red test lead banana plug into the (20A) jack.
