Abstract

The invention provides a high-precision program-controlled direct-current resistance box and a resistance correction method. The high-precision program-controlled direct-current resistance box comprises a controller, a keyboard module, a display module, a resistance network module and a motion control module; the keyboard module is connected with the input end of the controller, the keyboard inputmodule is provided with a keyboard, and the keyboard is used for inputting a resistance value; the display module is connected with the output end of the controller, and the display module is provided with a display screen; the resistance network module is provided with at least one rotary rheostat , and a rotary rheostat is provided with an adjusting rotary handle; the motion control module is connected with the controller, the motion control module is connected with motors, the number of the motors is the same as that of the rotary rheostats in the resistance network module, and the motorsare in transmission connection with the adjusting rotary handle; the resistance value can be adjusted instead of manual work, the adjusting speed is high, the accuracy is high, and the use efficiencyis improved; according to the resistance correction method, the output error of the resistance box can be reduced, and the precision of the resistance box is improved.

Description

technical field [0001] The invention belongs to the technical field of resistance boxes, and in particular relates to a high-precision program-controlled DC resistance box and a resistance correction method. Background technique [0002] Resistance boxes are widely used in scientific research, metrology, thermal engineering, factories, schools and other fields for electrical measurement, calibration, testing, etc. The old-fashioned resistance boxes are all manually operated with a decimal switch, which has many shortcomings such as low efficiency, cumbersome operation, high probability of human error, and inability to realize automatic testing. [0003] Therefore, it is necessary to design a high-precision program-controlled DC resistance box that can replace manual adjustment of the resistance value, with fast adjustment speed, high accuracy, and improved use efficiency to solve the current technical problems. Contents of the invention [0004] Aiming at the deficiencies...
