The multimeter consists of three main parts: the meter head, the measuring circuit and the transfer switch.
1. Table header
The head of the multimeter is a sensitive galvanometer. The dial on the head is printed with a variety of symbols, tick marks and numerical values. The symbol A-V-Ω indicates that this meter is a multimeter that can measure current, voltage and resistance.
2. Measuring circuit
The measurement circuit is a circuit used to convert various measurands into tiny DC currents suitable for meter measurement. It consists of resistors, semiconductor components and batteries.
3. Transfer switch
Its function is to select a variety of different measurement lines to meet the measurement requirements of different types and different ranges. The transfer switch is generally a circular dial with functions and ranges marked around it.
