Self-calibrating method of internal reference resistors of multi-range digital electronic measuring instrument

The invention relates to a self-calibrating method of internal reference resistors of a multi-range digital electronic measuring instrument, comprising the following steps of: on the basis of the design line of the traditional digital electronic measuring instrument, additionally setting an electronic switch and a self-calibrating program; setting a resistor with good long-term stability as an internal standard resistor in a set of internal reference resistors; when in a self-calibrating state, controlling the electronic switch by using the self-calibrating program to form different combinations so as to obtain comparing and measuring circuits among different reference resistors; and respectively and directly or indirectly comparing the reference resistors with the set internal standard resistor to measure respective actual resistance values and storing the actual resistance values in an internal storage for automatically correcting measuring results. Because only one standard resistor with good long-term stability needs to be adopted, other reference resistors are compared and calibrated with the standard resistor, and the method effectively reduces the requirements of other reference resistors, is beneficial to reducing the production cost and ensuring the measuring precision of each measuring process so that the calibration in the production process and the periodic calibration of users both are simpler and more effective and accurate.
