• 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 ≤3
• 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

• Measurement result = displayed value - resistance of shorted test leads
• Open-circuit voltage: About 1 V
• Accuracy guarantee: 1%~100% of range
• Overload protection: 1000 V
4. Continuity and diode
Range Resolution
0.001 V
• 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.

Resolution
Broken circuit: Resistance ≥70 Ω, no beep. Good continuity:
0.1 Ω
Resistance <50 Ω, audio/visual alarm.
Open-circuit voltage: About 3V.
For normal diodes, the buzzer will beep once.
For short circuit, the buzzer will beep for a long time.
