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 V AC 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 test probe tips to the circuit under test.
4.
Read the voltage in the display. The display will
indicate the proper decimal point, value and
symbol (AC, V, etc.).
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 mA range 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 A position and insert the red test
lead banana plug into the 20A jack.
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.
9. Read the current in the display. The display will indicate
the proper decimal point, value.
AC CURRENT MEASUREMENTS
WARNING:
To avoid electric shock, do not measure
AC current on any circuit whose voltage exceeds 250V
AC.
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 AC, set the
function switch to the mA range and insert the red test
lead banana plug into the (mA) jack.
3.
For current measurements up to 20A AC, set the function
switch to the A position and insert the red test lead
banana plug into the 20A jack.
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. And 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. The display will
indicate the proper decimal point, value.
8.
RESISTANCE MEASUREMENTS
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.
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
jack.
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.
4.
Read the resistance in the display. The display will indicate
the proper decimal point, value
CONTINUITY CHECK
WARNING:
To avoid electric shock, never measure
continuity on circuits or wires that have voltage on
them.
1.
Set the function switch to the position.
2.
Insert the black lead banana plug into the negative (-)
