Diode and Continuity
Range Description Remark
The approximate forward
voltage drop will be displayed
Open circuit voltage: about
1.5V
The built-in buzzer will sound
if the resistance is less than
about 30Ω
Open circuit voltage: about
0.5V
Overload Protection: 250V DC/AC rms
For continuity test: When the resistance is between 50Ω and 100Ω, the buzzer may sound or
may not sound. When the resistance is more than 100Ω, the buzzer will not sound.
