• Frequency measurement range: 40 Hz~1 kHz, input amplitude:
≥
10% of voltage range. Duty ratio is
for reference only
• Accuracy guarantee: 2%~100% of 60 mV range, 1 %~100% of other ranges; short circuit allows least
significant digit
≤

• Max input voltage: 1000 V (if the voltage is >1000 V the red indicator light will be on and the buzzer
will sound an alarm; if the voltage is >1010 V, the LCD will display “OL”)
• Overload protection: 1000 V

0.001 V
Open-circuit voltage: About 3V.
For normal diodes, the buzzer will beep once.
For short circuit, the buzzer will beep for a long time.
• Overload protection: 1000 V
• When the forward voltage drop is within 0.12~2 V, the buzzer will beep once.
When the forward voltage drop is <0.12 V, the buzzer will beep for a long time.
