Experimental design study of calibration meter with digital potential difference meter
FU Shi-min
Abstract：The operation trouble , time -consuming and system error of box -type potentiometer are ex-pounded.These problems can be solved if the digital potentiometer is used .UJ33D type digital potentiometer can occur and digital direct voltage measurements;Measurement range is 0-2500.0 mV, the accuracy level is 0.01, the minimum resolution is 0.01 mV.The principle of calibrating the electric meter with digital potentiometer ,The values of resistance R1 , R2 and Rs were studied, and the experimental design was analyzed .
