The data in this example was taken from devices that were exposed for several hours to 90%RH at 25°C in a test
chamber. The drift per hour decreases the longer the device is exposed to high humidity. The correction algorithm
compensates for the drift reasonably well. Since the error introduced by the saturation is relatively small, for some
applications compensation may not be necessary.
