warning, the resolution is less than 100. The buzzer continuously sounds, the
resolution is greater than SOO. The buzzer does not sound.
When the buzzer selects open circuit for sound warning, the resolution is greater
than SOO. The buzzer continuously sounds, the resolution is less than 1
on.
The buzzer does not sound.

(15) Diode Test
Range Resolution
Remark
Open-circuit voltage is around 3V. The forward voltage drop value of the measured
0.0001V
PN junction is approximately � 3V. When the buzzer activates, it will beep briefly
for the normal semiconductor junction; If the semiconductor junction shorts out, it will
beep continuously. Silicon PN junction drops between O.S~0.8V as the normal value.
• Overload protection: 1000V
