Notes on Use
3. Notes on Use
• The measurement unit consists of sensitive
precision optical and electronic parts.
Do not drop it. Protect it from being bumped or
jostled.
• Do not hold the unit by the measurement
aperture. You should not allow any foreign
objects to get into this opening.
• Do not expose the unit to direct sunlight for
extended periods of time. Do not store it in a hot
or dusty environment. The case that comes with
the unit offers the best protection when the unit
is being stored.
• Avoid prolonged high relative humidity and do not
allow condensation to form.
• Protect the measuring unit from moisture,
chemicals and corrosive vapors.
• The holder and the unit housing are resistant to a
number of solvents. However, we cannot
guarantee resistance to all chemicals. You
should therefore use a soft, moist cloth for
cleaning. For clean excessive dirt and dust, use
ethanol or cleaning alcohol.
Do not use any acetone!
• If you will not be using the measuring unit for an
extended period of time, remove the battery to
prevent it from leaking in the unit and thus
potentially causing damage.
