CLEANING THE INSTRUMENT
Your instrument requires very little maintenance to achieve years of reliable
operation. However, to protect your investment and maintain reading
accuracy, a few simple cleaning procedures should be performed from time
to time.
General Cleaning
Whenever required, the exterior of the instrument may be wiped clean with a
cloth dampened in water or a mild cleaner.
NOTE: DO NOT use any ketone solvents to clean the unit, this will cause
damage to the cover.
Cleaning the Optics
The optics and drive wheel assembly should be cleaned once a week in
normal environments, and more often in dirty or dusty environments.
1. Carefully lift instrument and insert tube from canned air into “front” strip
insertion slot.
2. With back and forth motion, spray clean, dry air from one side to the
other—do this several times. This should remove any accumulated dust
and lint from the optics and wheel assembly.
WARNING: DO NOT invert cans that use freon as a propellant, doing so
could cause damage to the optics assembly.
