What are the types of multimeters?
According to type, it is divided into: desktop multimeter and hand-held multimeter; according to structure, it is divided into: pointer multimeter and digital multimeter. According to the measurement principle, the pointer meter has magnetoelectric rectification type and electromagnetic rectification type. According to the structure of the meter, there are inner (outer) magnetic hairspring head and tension wire head. Meter, programmable digital meter with (without) interface, programmable digital meter connected to PC; divided into: general purpose and special purpose, conventional general electrical quantities such as measurable voltage, current, resistance and diode triode conduction voltage drop Such multimeters are generally used for special purposes, such as grounding resistance meters, insulation resistance meters, capacitance meters, micro-ohmmeters, etc.; according to the occasion, they are divided into: hand-held straight-type multimeters and hand-held clamp multimeters. The straight plate type can be used in more occasions such as: electrical and electronics, equipment maintenance, teaching and research, and various industries involving strong and weak currents. The clamp multimeter has a narrow application surface, mainly because power maintenance requires indirect measurement of large currents. Clamps are used. Shaped multimeter.
