Temperature and Humidity Variation
Changes in temperature and humidity will affect both resolution and
repeatability of imaging. Temperature variation should be limited to ±2
degrees Fahrenheit. Humidity variation should not exceed ±20 % RH.
Locating the instrument away from vents and air handlers will help meet
this goal.
