The behavior of the deviation during combined temperature- and vibration tests at usual levels has been investigated with 4 different accelerometers. It turned out that further parameters are jointly responsible for a reliable measurement or control of vibration level. For the daily use, the deviations of all parameters together are within the allowed tolerance of ±3dB. It is not necessary to adjust the sensitivity of an accelerometer in the daily use under extreme temperature. In special tests only the sensitivity needs to be adjusted. Several further parameters are able to influence the measurement considerably/far more.
