Development of New MotherChild Digital Multimeter

A new type of motherchild digital multimeter is introduced.Retaining the original survey function,this multimeter also gets the function of longdistance surveillance,with the aid of advanced frequencyhopping technology transmit the data which surveyed by the host to the slave,so that the observed value can be demonstrated on the liquid crystal screens of the host and slave simultaneously.Therefore,this kind of multimeter can be used in the high and small places and some other special work environment.Lowpower PIC single chip is used as the processor,to reduce energy consumption and increase battery life.
