WARNING: Handle lithium batteries
carefully, observe warnings on battery casing.
Dispose of in accordance with local regulations.
RECONDITION PROCEDURE
Exposure of the internal sensor to chemical vapours
may interfere with the internal sensor and cause
inaccurate readings to be logged. In a clean
environment, this will slowly rectify itself. However,
exposure to extreme conditions or chemical vapours
will require the following reconditioning procedure to
bring the internal sensor back to calibration state.
80°C (176°F) at<5%RH for 36h (baking) followed by
20-30°C (70-90°F) at>74%RH for 48h (re-hydration)
High levels of pollutants may cause permanent
damage to the internal sensor.
