What is Temperature Drift?

Temperature of the device can influence the measurements. Temperature drift variations primarily happen because the ambient temperature quickly changes and the device is too cold or too hot. Allowing the device to stabilize before using it, and performing a calibration will reduce temperature drift errors. 

Temperature drift can be solved by good ventilation, which is influenced by the design of the device as well as its proper installation. Ventilation usually ensures a uniform temperature in all critical modules across the instrument reducing the temperature drift to a minimum.
