Digital display instrument is a kind of analog digital converter and the decimal digital form to show the value of the measured instrument,
it is with various sensors, distribution devices, can display a variety of different parameters. Digital instrument has advantages of high precision,
complete function, high speed, strong anti-interference ability, small volume, low power consumption, visual reading,
and can measure the results in the form of digital input computer, so as to realize the automation of the production process.
