Wire testers, also called wire testers, are now generally divided into three types.The first kind is to test conduction, dislocation, short circuit, open circuit, Its advantages are accurately determine the AB end error, With favorable price, fast speed, large-screen, It makes viewing results more intuitive.
The second type is added one extra unilateral test / insulation / high voltage and other functions; this tester use more for the headset cable, the test speed is faster than the ordinary high-pressure equipment on the market, AB-end judgment is more accurate.
The third type is to use for testing the electronic wire with components, using the four-wire test method to accurately measure the parameters of the components!
