LCD Screen: The LCD screen greatly improves the reading experience, the illuminated numbers and letters with black background make it very easy to read, even in direct sunlight or low light. 3-line display: large triple line high resolution display can show 3 test results on the screen, voltage, frequency and analog bar. 8 LED indicators: 8 LED indicators in 3 colors make it easy to judge the detected voltage. Adjustable Sensitivity: Adjustable sensitivity makes measurement more convenient, when setting low sensitivity, it can more accurately distinguish the specific situation in complex lines. [Built-in Multimeter]: The built-in multimeter design of the voltage detector not only greatly expands the test applications, but also allows you not to worry about the multimeter consuming too much space.
