Battery Replacement
If the green READY LED flashes or does not illuminate, the batteries need
to be replaced. The battery compartment is located at the rear of the EZ40.
Replace the three “C” batteries by sliding 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 only with a damp cloth as needed. Do not apply abrasive,
solvents, or other cleaners to the surface of the meter or sensor. Store with the batteries
removed and avoid extreme temperature and humidity.
