Resistance
TO AVOID ELECTRICAL SHOCK AND INJURY, TURN
OFF POWER TO THE CIRCUIT AND DISCHARGE ALL
CAPACITORS BEFORE MEASURING RESISTANCE.
WARNING:
1.Insert the black test lead into “ COM” jack and red test
lead into “ INPUT” jack.
2.Turn the rotary switch to the position.
3.Connect the test leads across the circuit to be tested.
4.Read the measured resistance value on the display.
Note:
•
If the resistance is too high or the test leads are
disconnected, the display shows “ OL ”.
• The meter may take several seconds to get a steady
reading if the resistance being measured is more than
1M
Ω .This is normal for high resistance circuits.
Continuity
TO AVOID ELECTRICAL SHOCK AND INJURY, TURN
OFF POWER TO THE CIRCUIT AND DISCHARGE ALL
CAPACITORS BEFORE MEASURING CONTINUITY.
WARNING:
1.Insert the black test lead into “COM” jack and red test
lead into “INPUT” jack.
2.Turn the rotary switch to the
position.Press “FUNC”
to switch to continuity mode.
3.Connect the test leads across the circuit to be tested.
4.Read the measured resistance value on the display.
5.If the resistance is less than 50
Ω , the meter’s buzzer
will sound.
Note:
If the resistance is higher than 60M Ω or the leads are
disconnected, the display shows “ OL ”.
Capacitance
TO AVOID ELECTRICAL SHOCK AND INJURY, TURN
OFF POWER TO THE CIRCUIT AND DISCHARGE ALL
CAPACITORS BEFORE MEASURING CAPACITANCE.
WARNING:
1.Insert the black test lead into “ COM” jack and red test
lead into “ INPUT” jack.
2.Turn the rotary switch to the position.Press " FUNC "
twice to switch to capacitance mode.
3.Connect the test leads across the circuit to be tested.
4.Read the measured resistance value on the display.
Note:
•
For better accuracy on measurements below 10nF, touch
the tips of the leads together before measurement and
subtract the distributed capacitance of the meter from the
actual measurement.
• For measurements on large capacitances, allow up to 30
seconds for the reading to stabilize.
Diodes
1.Insert the black test lead into “ COM” jack and red test
lead into “ INPUT” jack.
2.Turn the rotary switch to the position.Press " FUNC "
three times to switch to diode mode.
3.Connect the red lead to the anode (+) and the black
lead to the cathode (-).
4.Read the measured forward biased voltage drop on the
display.
Note:
•
If the leads are connected backwards or to an open
circuit, the display will show “OL” .
