Abstract: According to the fact that the isolated analog signal conditioning modules has problems like type redundancy, multiplex parameters, heavy utilizing rate and manual evaluation is timeconsuming, laborious, inefficient and fallible, based on the VEE Pro softwareexploiting platform, the system of automatic calibration of isolated analog signal conditioning module is developed. The system contains three main moulds: instrumental information recording, calibrating and printing. The test data can be displayed in real time, and the data can be processed and archived automatically. The results show that the system is easy to operate. It improves working efficiency, reduces manmade errors and ensures the veracity of the test data.

Key words: Isolated analog signal conditioning module, Linearity frequency response, DC linearity error, Automatic calibration, Software design
