Environment

The performances of an optical sensor greatly depend on the conditions in
which it is used.
The contractual characteristics are specified in the manual that goes with
each sensor of the LDS series.
The operating limits of the LDS1000 Controller are the following:
• Operating temperature
• Humidity
• Storage temperature
Refer to the paragraph entitled "Specification Validity" in each user's
manual for the performances of the sensors according to the conditions of
use.

Analog Outputs

Analog outputs are only available if the option has been chosen.
• Refresh frequency
• Digital low-pass filter
• Output range
• Scale factor
• Resolution
• Electronic noise
• Distortion
• Maximum Offset
• Output impedance
• Discrepancy equivalent to a pure delay of 1.1 msec (without integration).
• Attenuation equivalent to the one of an order 1 low-pass filter with
600 Hz cutoff frequency.
The analog outputs use an intermediary calculation stage that is based
on a sample at 2000 Hz. This will limit the use of the LDS sensor for stu-
dying signals that do not have a significant spectral component over
1000 Hz (this sort of component would find themselves "withdrawn" and
would appear for lower frequencies).
