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 highest V AC position.
2. Insert the black test lead banana plug into the
negative (COM) input terminal. Insert red test lead
banana plug into the positive (V) input terminal.
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. Reset the
function switch to successively lower V AC
positions to obtain a higher resolution reading.
The display will indicate the proper decimal point and value.
DC CURRENT MEASUREMENTS
1. Insert the black test lead banana plug into
the negative (COM) input terminal.
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) input
terminal.
3. For current measurements up to 10A DC, set the function switch
to the 10A range and insert the red test lead banana plug into the
(10A) input terminal.
4. Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current.
5. 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.
6. Apply power to the circuit.
7. Read the current in the display. For mA DC measurements, reset
the function switch to successively lower mA DC positions to
obtain a higher resolution reading. The display will indicate the
proper decimal point and value.
RESISTANCE MEASUREMENTS
1. Set the function switch to the highest W
position.
2. Insert the black test lead banana plug into
the negative (COM) input terminal Insert the
red test lead banana plug into the positive
W input terminal.
3. Touch the test probe tips across the circuit
or part under test. It is best to disconnect
one side of the part under test so the rest of
the circuit will not interfere with the
resistance reading.
CAUTION:
Do not make current measurements on the 10A
scale for longer than 30 seconds. Exceeding 30 seconds may
cause damage to the meter and/or the test leads.
WARNING:
To avoid electric shock, disconnect power to the
unit under test and discharge all capacitors before taking any
resistance measurements. Remove the batteries and unplug
the line cords.
