The development trend of digital multimeter
Integrated
The handheld digital multimeter uses a single-chip A/D converter, and the peripheral circuit is relatively simple, requiring only a small number of auxiliary chips and components. In recent years, dedicated chips for single-chip digital multimeters have been continuously developed, and a relatively complete automatic range digital multimeter can be formed by using one IC, which has created favorable conditions for simplifying design and reducing costs.
Low power consumption
New digital multimeters generally use CMOS large-scale integrated circuit A/D converters, and the power consumption of the whole machine is very low.
The author introduced above is only the main principle of choosing a multimeter, without considering the price factor and other human factors. It is also necessary for the user to select the multimeter according to the actual needs and actual conditions.
