Features: 4.4 Inch Touching Screen: This multimeter adopts a 4.4inch touching screen for you to operate this tool more smoothly and see teh detecting data more clearly. Input Jack Indicator: When the gear is changed, the comesponding inout light will light to prompt to insert the probes the cormesponding jack, so this function can effectively avert wrong holes. VFC Function: The traditional multimeter will give wrong readings when measuring the variable frequency, and it is more time-consuming to solve the problem, with this function, you can solve this problem easily. Voice Control&Broadcast: This function is very suitable when you can't observe the test results directly, you can say "hello, lucy, voltage" to the instrument and it will automatically broadcast the detected voltage for you. Multiple Measurement Functions: This multimeter supports voltage measurement, current measurement, resistance, diode and temperature measurement. Backlight&Flashlight: This two functions allows you to use it normally in low-light environments or even in total dark environment.
