The instrument is equipped with five wires, which can easily access the internal circuits of cars, cars and motorcycles. It is used to monitor voltage and master voltage in time. It can also be used for voltage and current measurement in other products. IC uses the chip, which has a longer production life and better dust -free workshop quality. Value is accurate and easy to read.The appearance adopts standard size and is convenient for installation. The instrument can be used for both uses, but also control the voltage and current at the same time.
