Precautions:
There is high-voltage on PCB on this voltmeter's back, it is dangerous to touch PCB and components. So we suggest that electronic enthusiasts and ordinary consumers don't use this, please be careful when purchasing.
This voltmeter uses capacitance to achieve voltage step-down conversion before measurement. This means that it can not be used in inverter, electronic speed governing, SCR dimming, UPS and similar applications where sinusoidal wave distortion or phase shifts occur. Those scenarios can lead to permanent damage to this device and/or inacurrate readings.
This voltmeter is none of moisture-proof, waterproof, shockproof, oil-proof, please be careful while handling and using.
