②Automatic gear : Only voltage , resistance and continuity test gears are
identified automatically.
③ When measuring voltage, AC/DC voltage is identified automatically.
④ When measuring, if the resistance at both ends is less than 50 Ω, the buzzer
will ring.
Voltage measurement
①Switch to the voltage gear, connect the
red test pen to the input terminal
and the black test pen to the input terminal
.
Resistance measurement
①Switch to the resistance gear and
connect the red test pen to the input
terminal aand the black test pen
to the input terminal .
②During measurement, the range gear will
be automatically identified.
Diode /Continuity test measurement
①Switch to diode/continuity test mode,
connect the red test pen to the input
terminal and the black test pen to
the input terminal .The multimeter
will automatically identify the current
measured signal based on the voltage and
resistance of the measured object.
② Measuring continuity test, when the resistance is less than 50 Ω, the buzzer
will ring.
③ When measuring the diode, the screen displays a forward bias voltage. If the
polarity of the test wire is opposite to that of the diode, or the diode is damaged,
the screen displays "OL".
