PULSE WIDTH
•
Overload protection: 1000V.
•
When the rise time is less than 1µs, the signals centre on the trigger level.
•
The pulse width is greater than 2µs for 10Hz to 200kHz. The pulse width depends
on signal frequency.
CONTINUITY TEST
Range Resolution
Remark
0.01Ω
Open circuit voltage is around 3V. When the buzzer selects
short circuit for sound warning, the resolution is less than
10Ω. If the buzzer continuously sounds, the resolution is
greater than 50Ω. The buzzer does not sound.
When the buzzer selects open circuit for sound warning,
the resolution is greater than 50Ω. The buzzer continuously
sounds, the resolution is less than 10Ω. The buzzer does not
sound.

Overload protection: 1000V.
DIODE TEST
Range Resolution
Remark
0.0001V
Open circuit voltage is around 3V. The forward voltage drop
value of the measured 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 0.5~0.8V as the normal value.
