With the rapid growth of environmental test equipment measurement business, there are a large number of automatic calibration software for environmental test equipment in the market, but these software generally have problems such as incomplete function, single procedure and inconvenient operation. In view of the lack of software on the market, this paper designs an automatic test software for environmental test equipment, which has good compatibility, supports multi procedure coverage and multi parameter calibration function, so as to provide strong guarantee for the high efficiency and high accuracy measurement of environmental test equipment.
