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 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.).
5.
Press the MODE button until “AC” appears in the
display.
DC CURRENT MEASUREMENTS
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.
1.
Insert the black test lead banana plug into the negative
(COM) jack.
2.
For current measurements up to 4000
A DC, set the
function switch to the
A position and insert the red test
lead banana plug into the (
A) jack.
3.
For current measurements up to 400mA DC, set the
function switch to the mA range and insert the red test
lead banana plug into the (mA) jack.
4.
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 10A jack.
5.
Press the MODE button until “DC” appears in the
display.
6.
Remove power from the circuit under test, then open up
the circuit at the point where you wish to measure
current.
7.
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.
8.
Apply power to the circuit.
9. Read the current in the display. The display will indicate
the proper decimal point, value and symbol.
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 10A 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 4000
A AC, set the
function switch to the
A position and insert the red test
lead banana plug into the (
A) jack.
3.
For current measurements up to 400mA AC, set the
function switch to the mA range and insert the red test
lead banana plug into the (mA) jack.
4.
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 10A jack.
5.
Press the MODE button until “AC” appears in the
display.
6.
Remove power from the circuit under test, then open up
the circuit at the point where you wish to measure
current.
7.
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.
8.
Apply power to the circuit.
9.
Read the current in the display. The display will
indicate the proper decimal point, value and
symbol.
