Abstract

The invention discloses a variable resistance load box for detection; the variable resistance load box for detection comprises an access end, the first resistor, the second resistor, the third resistor, the first exit end, the second exit end and the third exit end; the access end is electrically connected with the input ends of the first to third resistors; the first exit end is electrically connected with the output end of the first resistor; the second exit end is electrically connected with the output end of the second resistor; the third exit end is electrically connected with the outputend of the third resistor. The variable resistance load box for detection uses the first to third resistors to respectively a fixed value small resistance, a fixed value large resistance and a variable value resistance, thus satisfying different loading demands; the variable resistance load box for detection is novel in structure, easy to operate, accurate in detection, stable in performance, convenient and practical, thus providing wide market prospects in promotion of the variable resistance load box for detection.

Description

technical field [0001] The invention relates to the detection field, in particular to a variable resistance load box for detection. Background technique [0002] Product testing covers various industries such as electronics, toys and gifts, textiles, clothing and shoe materials, food and food contact materials, automobiles, environmental protection, industrial parts, medical devices, and new energy. Product testing directly affects product quality, and only high-quality testing devices can support accurate, fast and efficient testing technology. [0003] Most of the existing loads use fixed-value resistors. When different loads are required, different resistors are replaced. The replacement is cumbersome and inefficient, which is not conducive to accurate, fast and efficient detection. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a variable resistance load box for detection, by using the first resistance, th...
