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 30Ω and
100Ω, the buzzer may sound or may not sound. When the
resistance is more than 100Ω, the buzzer won’t sound.
