The 825 meter is designed to be recalibrated with water for
safe handling. Over time, the chamber inside the meter will
wear. Recalibrating the meter with clean water will insure that
Table #1 is most accurate.
You will need a container of known volume, at least 5 gallons
or larger. Do not exceed a 60 gallon container.
