Objective A temperature-humidity-altitude testing equipment was analyzed for solution of its temperature excursion during low temperature-altitude test. Methods For studying and analyzing the reason of temperature excursion during the low temperature-altitude test using a domestic temperature-humidity-altitude testing equipment,this paper found out the causes for temperature excursion during the low temperature-altitude test,and provided the recast method of the test hole’s sealing cover plate and the reference data of parameter setting for equipment control. Results Temperature change was smaller than ± 3℃at low temperature(-55℃)and low air pressure(11.9 kPa). Conclusion We have successfully solved the temperature excursion problem of low temperature-altitude test, through the device control parameter replacement,especially by a fitting program test. The test results met the requirements of test technology conditions,saved the manpower,and won time for product delivery.
