Measurement Conditions
Operating the instrument in extreme environmental conditions
may cause substantial errors. Examples include bright sunshine,
extreme temperatures, poor surface reflections and low batteries.
Under these conditions applying a reflective sheet to the target
surface may improve results.
Transparent or clear measurement target surface (such as water,
clear glass, etc.) may lead to inaccurate measurements.
Inaccurate measurements can also result if the target surface
reflects light strongly.
Very dark surfaces or surfaces that do not reflect light well can
cause longer measurement times.
Maintenance
Do not store the instrument in environments of high temperature
and/or humidity. Remove the batteries if the meter will be out of
use for an extended period and stored it in a cool and dry place.
Keep the instrument surface clean. Do not clean the instrument
with corrosive or caustic cleaners. Treat the laser and focusing
lens as you would the optical lens of a camera.
