The maintenance of the pen should not be considered such a simple matter. It is not just a matter of connecting the wires to use it normally. This is a wrong viewpoint, and the quality of the pen determines the size of the measurement error.
A multimeter can not only be used to measure the resistance of the object being measured, but also to measure AC and DC voltage. Even some Multimeter can measure the main parameters of transistors and the capacitance of capacitors. Fully mastering the use of a multimeter is one of the most basic skills in electronic technology.
Digital multimeter, also known as multimeter, Multimeter, multi-purpose electricity meter or three purpose electricity meter, is a multi-purpose electronic measuring instrument, generally including ammeter, Voltmeter, Ohmmeter and other functions.
A multimeter is an instrument used to measure AC/DC voltage, resistance, DC current, etc. It is a necessary tool for electricians and radio production.
Whether it's a digital table or a pointer table, the usage is the same. To measure whether a wire is good, we actually use a multimeter to measure its resistance value. If the resistance value is infinite, it means it is broken. A resistance value close to 0 is good.
