SP1500B multi-function to count machineis adopt what microprocessor development complete.The biggest characteristics in this instrument is an adoption to count down to count the technique, measuring the accuracy high, measure the frequency scope breadth, the intelligent degree is high.(20 mVrmses below)The CPLD machine piece application make instrument dependable increased consumedl
That machine places before electric circuit contain low the filter of authority ,decline reduce the machine, and the index number shows, in keeping with post and tele correspondence, broadcast television, school, graduate school and work mineral business enterprise section grinds and produce it use
