Main Features:
● Display: 0.39 inches of LED digital display， voltage is red， current is green
● Measurement speed: Approximately 2 times per second
● Power line， measuring line length: About 150mm
● Sunlight: No direct exposure

Precautions:
● This meter uses the capacitor step - down principle， because the higher the frequency the smaller the impedance of the capacitor， it is not suitable for use in high - frequency electronic speed control， non - mains frequency sine wave， or other high - frequency components occasion， or else it is easy to burn.
● The instrument wiring sequence is: First connect the current loop line， 220V voltage finally connected， after turning on the 220V power supply， do not touch any components and circuits， to avoid electrical shock hazard.
