Maintenance
Battery Replacement
When the battery power falls low, the low battery icon will appear on the LCD. Replace
the 9V battery by removing the Phillips screw on the battery compartment door and
accessing the battery compartment. Ensure that the compartment cover is securely
fastened when finished.
Cleaning and Storage
Wipe the meter and vane with a damp cloth as needed. Do not apply abrasive, solvents, or
other cleaners to the surface of the meter or vane. Store with the battery removed and
avoid extreme temperature and humidity.
