Temperature chamber operation confirmation procedure

positioning of main and additional transducers

Environmental factors may affect the conditions inside of the temperature chamber in the course of tests performance. In particular, minor fluctuations in atmospheric pressure may result in fluctuations of relative humidity in the working space of the temperature chamber. That is exactly why the scope of instruments for system performance confirmation includes absolute pressure sensor ZET 7012-A (160 kPa).
