Digitizing instruments that use digital circuitry to count the number of pulses passed for a given time and display the count result. Electronic counters are the basis of other digital instruments. In its input channel access to a variety of analog-digital converter, and then use the corresponding transducer can be made of a variety of digital instruments. The advantages of electronic counter measurement accuracy, wide range, multi-function, simple operation, fast measurement, direct display of digital, and easy to automate the measurement process, in industrial production and scientific experiments have been widely used.
