If the outside of the probe becomes dirty, you may clean it using a slightly damp cloth.
It is not recommended that you clean inside the probe. If the inside does get dirty or
dusty, the probe should be returned to GrayWolf for servicing.
Summary of Cautions
Avoid operation in direct sunlight as %RH measurements may become erratic.
Do not immerse the probe in water.
This is a precision instrument. Do not drop the probe or subject it to undue vibration
or shock.
When not using the probe for a period of time, store it in a cool, dry, dust-free
environment. The recommended storage temperature is 32ºF to 70ºF (0ºC to 21ºC).
If the storage period will be more than four weeks, remove the batteries from the
probe before storing.
Do not place the probe in an environment where condensation will form on it. The
CO
2
sensor is an optical sensor which uses an active detector and a reference
detector for stable long-term readings. If condensation has formed on one of the
detectors or if there are temperature differences between the two detectors, CO
2
readings may be erratic until the sensor has stabilized to its new environment.
