7. Operating Instructions
Warning:
Risk of electrocution. High-voltage circuits, botn AC and DC, are very dangerous
and should be measured with great care.
• Always
turn the function switch to the OFF position when the meter is not in use.
•
If
"OL"
appears in the display during a measurement, the value exceeds the range you
have selected. Change to a higher range.
7.1 DC voltage Measurements
Caution:
Do not measure DC voltages if a motor
on the circuit is being switched
ON
or
OFF.
Large
voltage surges may occur that can damage the
meter.
•
Set the function switch to the
"DC"
position.
•
Insert the black test lead banana plug into the
negative
COM
jack.
Insert the red test lead banana plug into the
positive
V
jack.
•
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.
•
Read the voltage in the display.
7.2 AC Voltage Measurements
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.
•
Set the function switch to
"AC"
position.
•
Insert the black test lead banana plug into the
negative
COM
jack.
Insert red test lead banana plug into the
positive
V
jack.
•
Touch the black test probe tip to the neutral
side of the circuit.
Touch the red test probe tip to the " hot ” side
of the circuit.
•
Read the voltage in the display.
7.3 AC/DC Current Measurements
Caution:
Do not test 10A current measurements for longer than 30 seconds. Exceeding
30 seconds may cause damage to the meter and/or the test leads.
•
Insert the black test lead banana plug into the negative
COM
jack.
•
For current measurements up to 6000μA AC/DC, set the function switch to the μA
position and insert the red test lead banana plug into the μA/mA jack,press mode button
to select AC or DC.
•
For current measurements up to 600mA DC, set the function switch to the mA position
and insert the red test lead banana plug into the μA/mA jack ,press mode button to select
AC or DC.
