③
When the resistance is greater than 50Ω, it will
automatically jump to resistance measurement.
④
If the measured value is equal to the nominal
resistance of the resistor or within the range of error, the
resistor is functioning correctly.
If there is a large deviation between the nominal
resistance and the measured resistance, the resistor is
bad.
If the measured resistance is infinite (open circuit),
zero (short circuit), or unstable, it means the resistor is
damaged and can no longer be used.
In general, if the resistance value of fuse, wire,
household light bulb or other items exceeds 50Ω, it
indicates that the inside of the item has been damaged
or burned out.
4.4 Continuity Test:
①
Deenergize the circuit you will be testing.
②
Place the test leads on both sides of the object to be
measured.
③
When the measured resistance of the circuit is less
than 50Ω, it will automatically switch to the continuity
mode. The buzzer will sound and the indicator will
light up in green. If the resistance value is greater than
50Ω, it indicates that the object to be measured has
been damaged. It automatically switchs to resistance
measurement.
5)
When the measurement is completed, disconnect
the test leads from the measured object.
WARNING
1.A voltage higher than 600V cannot be measured
otherwise the meter may be damaged.
2.Pay special attention to safety when measuring
high voltage to avoid electric shock or personal
injury.
Note
:
Minimum measurable voltage: 0.5V.
