The ATS Dimensional Lab lives within a room designed for high precision environmental control. The lab is maintained at 68 ° F within +/- 2.0 ° F and the resting humidity stays within a range of 30-55% as appropriate. The lab floor contains isolation joints that reduce any effects caused by vibrations. Feeler gages are thoroughly cleaned and placed into the Dimensional lab to stabilize to a specific temperature for at least 24 hours before calibration begins.
