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.
When using a multimeter to measure the line, the main purpose is to check whether there is any damage to the line. You just need to unscrew the BNC head and use a multimeter to set it to the on/off position. One end is connected to the middle signal core
