Environmental Considerations
The instrument is designed to operate at ambient temperatures between +5 and +40 ºC, and should be protected
from direct sunlight and moisture.
Optical measurement instruments are sensitive to extremes in environmental conditions like high temperature, humid-
ity and contamination. Measurement results can be corrupted under such extreme conditions.
Protect the device from high humidity, high temperature, direct sunlight and contamination.
Do not use the instrument immediately after having taken it from a cold into a warm environment. Under certain cir-
cumstances, condensation could develop and may cause corruption of the measurement results. Allow the device to
adjust to room temperature before switching it on.
Do not use the instrument in powerful magnetic, electromagnetic and electrostatic fields. These disturbances may
corrupt the measurement results.
