7.
Make sure all covers and hoods for the photometer and control unit, and
all closures on them, are properly locked.
No particular conditions are required for storage of the equipment, but do ob-
serve the following points:
Because the photometer and control unit contain electronic components,
the conditions should meet the normal requirements for such components.
In particular, the storage temperature should be within the -20 .. +50°C
range.
All components that have come into contact with the medium during oper-
ation must be dry and clean for protracted storage or shipment.
The photometer, control unit and accessories must be protected against
weathering, condensing moisture and aggressive gases while in storage.
