Embodiment Construction
[0054] The present invention will be described below in conjunction with the accompanying drawings.
[0055] figure 2 It is a flow chart of the verification method of the high-accuracy DC current comparator for resistance measurement of the present invention. First connect ten resistors with the same nominal value (resistance value is R A ) are connected in series and parallel to form a series resistance array and a parallel resistance array respectively. The parallel resistance array uses a four-terminal lead node structure to connect the nodes at both ends of each parallel resistance, and when the resistance arrays are connected in parallel, the external short circuit is used to set the short circuit compensation, and then through the DC The current comparator is used for proportional measurement, and the DC current comparator can obtain the series-parallel proportional display respectively; three or more groups of resistors are connected in series and parallel, and then t...
