Working specifications
Voltage AC
Voltage(symbol: V), also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
LED indicator
The device has a built-in LED indication with a variety of uses.
Frequency
Frequency describes the number of crests of a wave that move past a given point in a given unit of time. The most common unit of frequency is the hertz (Hz ), corresponding to one crest per second. The frequency of a wave can be calculated by dividing the speed of the wave by the wavelength.So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.
