Measurement and storage conditions
Avoid sudden changes in light conditions while
testing. The ashlight of a camera, for exam-
ple, can lead to incorrect results.
Keep the meter away from very strong light
sources (e.g. direct sunlight, studio lighting,
etc.). These may stop the meter from function-
ing correctly and lead to error messages.
11.4 Sources of interference
Strong electromagnetic elds may interfere
with the proper operation of the meter. Do not
use the meter in close proximity to a strong
electromagnetic eld.
To avoid electrostatic discharge, do not use
the meter in a very dry environment, especially
one in which synthetic materials are present.
