DIGITAL MULTIMETER

Multimeter is also known as multiplexing table, multi-purpose table, three-purpose table, complex table, etc., is an indispensable measuring instrument in power electronics and other departments, generally to measure voltage, current and resistance as the main purpose. Multimeters are classified into pointer multimeters and digital multimeters by display mode. Is a kind of multi-functional, multi-range measuring instrument, general multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio electrical equality, some can also measure AC current, capacitance, inductance and some parameters of the semiconductor (such as β).

The basic function

The multimeter can be used to measure not only the resistance of the measured object, but also the AC and DC voltage. Even some multimeters can also measure the main parameters of the transistor and capacitor capacitance. Fully proficient in the use of multimeter is one of the most basic skills of electronic technology. The measurement value of the Digital Multimeter is displayed by the LCD directly in the form of digital, easy to read, and some also have voice prompt function. Multimeter is a common meter head, set voltmeter, ammeter and ohm meter in one meter.

The DC current range of the multimeter is a multi - range DC voltmeter. The meter head in parallel closed circuit voltage divider can expand its voltage range. The DC voltage range of the multimeter is a multi - range DC voltmeter. The series voltage divider of the meter head can expand its voltage range. Different partial voltage resistance, the corresponding range is also different. The head of the multimeter is the magnetoelectric system measuring mechanism, it can only through DC, the use of diode will be AC into DC, so as to realize the measurement of alternating current.
