How do environmental changes affect the CI-203?

The CI-203 can be affected by rapid changes in humidity and temperature, such as when moving from an air-conditioned vehicle to a hot field habitat or greenhouse. With the rapid shift in the environment, there is a small chance condensation may form causing a temporary freeze-up of the CI-203. To remedy this, it is advised to wrap the instrument in a plastic bag and allow it to equilibrate with the ambient temperature when changing the instrument's environment. If the environmental change is small the user should not need to allow the unit to stabilize as long and should not incur a unit freeze-up.
