the corresponding functional gear
according to the required measure-
ment parameters during measure-
ment.
Automatic gear:
and when measuring voltage, it will automatically identify AC voltage/DC
voltage.
Diode Continuity test gear:
resistance value is less than 50 Ω, the buzzer will ringing and the screen will
display positive bias voltage when measuring the diode. If the polarity of the test
wire is opposite to that of the diode, or the diode is damaged, the screen will
display "OL".
LIVE (live wire detection)v：

to switch to the LIVE gear,
and use a red test pen to detect a live
wire when encountering a live wire.
The screen displays as shown in the
