Introduction 1
Maintenance
Before using the instrument, read and follow the following maintenance instructions:
•
Do not leave the instrument in direct sunlight or in a closed vehicle for
prolonged periods. Overheating the instrument may reduce its efficiency.
•
If the NPL-322 instrument has been used in wet conditions, immediately wipe
off any moisture and dry the instrument completely before returning the
instrument to the carrying case. The instrument contains sensitive electronic
assemblies which have been well protected against dust and moisture.
However, if dust or moisture gets into the instrument, severe damage could
result.
•
Sudden changes in temperature may cloud the lenses and drastically reduce the
measurable distance, or cause an electrical system failure. If there has been a
sudden change in temperature, leave the instrument in a closed carrying case in
a warm location until the temperature of the instrument returns to room
temperature.
•
Do not store the NPL-322 instrument in hot or humid locations. In particular,
you must store the battery pack in a dry location at a temperature of less than
30 °C (86 °F). High temperature or excessive humidity can cause mold to grow
on the lenses. It can also cause the electronic assemblies to deteriorate, and so
lead to instrument failure.
•
Store the battery pack with the battery discharged.
•
When storing the instrument in areas subject to extremely low temperatures,
leave the carrying case open.
•
When adjusting the leveling screws, stay as close as possible to the center of
each screw’s range. The center is indicated by a line on the screw.
•
If the tribrach will not be used for an extended period, lock down the tribrach
clamp knob and tighten its safety screw.
•
Do not use organic solvents (such as ether or paint thinner) to clean the
non-metallic parts of the instrument (such as the keyboard) or the painted or
printed surfaces. Doing so could result in discoloration of the surface, or in
peeling of printed characters. Clean these parts only with a soft cloth or a
tissue, lightly moistened with water or a mild detergent.
•
To clean the optical lenses, lightly wipe them with a soft cloth or a lens tissue
that is moistened with alcohol.
