Product Feature: The transmitter is integrated with the function of AC/DC voltmeter, which can measure 12 to 400V AC/DC voltage on a linear basis. The man-machine interface of our cable detector is very friendly, and the button operation is convenient.When the button is pressed, a buzzer is used to prompt the button to effectively display the effect.The transmitter and receiver are equipped with LED lighting. The transmitter can not only transmit signals, but also an AC and DC voltmeter. When detecting a live line, it will display a lightning warning symbol and display the voltage brought by the line, and it can also display whether it is AC or DC. Through the display you can observe whether the transmitter is in the launching state and whether the launch is normal, which will make you appear more confident during detection operations. You can judge the detection effect by sound without observing the display screen, thus making your detection work easy.In order to hear the sound from the speaker in a noisy environment, the developers designed a larger sound power. Of course, in special occasions such as hospitals, you can choose the mute function.
