KKM100-ENG has a voice broadcast function! This tool is pen-type intelligent multimeter, no need to turn the dial to select the function, according to the input voltage / resistance / difference, the meter will automatically identify and measure, the performance of this machine stable, high precision, high reliability, clear reading, overload pro-tection function, come on and try it, it will not let you down. Features: It is small in size and easy to carry, you can even put it in to your pocket to carry it to anywhere you want to use it. It not only the multimeter, but also the voltage test pens, for the kkm100 type, it also has the phase sequence measurement function which the kkm99 not has. The kkm99 with positive display screen, and the kkm100 has the color screen, you can choose the type you like. Wide application: It is a tool meter with fine performance, an utility tool for laboratories, factories, radio enthusiasts and families. This series of meters can automatically identify direct current voltage, AC voltage, resistance, without any switching, and can also be manually switched to measure capacitance, diode, continuity test, non-contact voltage measurement, zero-live line measurement, and other parameters. Automatic power off function, without any operate in 5 minutes, it will automatic shutdown.
