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.).
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 DC current measurements, set the function switch to
the DC 10A position and insert the red test lead banana
plug into the 10A jack.
3.
Remove power from the circuit under test, then open up
the circuit at the point where you wish to measure
current.
4.
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.
5.
Apply power to the circuit.
6.
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 ACcurrent measurements , set the function switch to
the AC 10A position and insert the red test lead banana
plug into the 10A jack.
3.
Remove power from the circuit under test, then open up
the circuit at the point where you wish to measure
current.
4.
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.
5.
Apply power to the circuit.
6.
Read the current in the display. The display will
indicate the proper decimal point, value and
symbol.
