Maximum Proteus - Manual (Page 3)

IMPORTANT ADDITIONAL INFORMATION
Components: Along with the indicator, the following components are included with this instrument:
Brass Case: Your brass case is solid brass A70-30 Holloware quality, with a durable lacquer
finish. It is in fact a piece of jewelry and should be treated as such. It should be cleaned at least
once a week to keep airborne pollutants (dust, etc…) and any moisture from collecting on the case
thereby attacking the lacquer. At no time should you use an abrasive cleaner or cloth on the brass
case. Simply use a soft cloth or soft paper towel with a mild glass cleaner to wipe the case clean.
If your instruments are in a summer home, and you are not able to clean them regularly, simply lay
a small cloth or towel across the top two-thirds so that dust cannot settle on the finish.
Specifications: All instrumentation or measuring devices have accuracy tolerances and
specifications. Making comparisons between different pieces of equipment is appropriate provided
the specified accuracies of both are known.
