ASTECH LDM41A - Laser Classification

Safety Instructions LDM41A and LDM42A Manual

 Repair work on the LDM41A and the LDM42A must not be carried
out by anyone other than authorized personnel.
 Refrain from using the LDM41A and the LDM42A without certified
protection in an explosive environment
 Measurement with the LDM41A and the LDM42A pointed at the
sun or other strong light sources may produce faulty results
 Measurement of targets with poor surface reflectance in a strongly
reflecting environment may also result faulty measurements.
 Measurement of strongly reflecting surfaces may deliver faulty
results.
 Measurement performed through transparent optical media, for
example glass, optical filters, Plexiglas, etc. may equally produce
incorrect results.
 Measurement on translucent objects (materials allow light to pass
through, but are not transparency, e.g. polystyrene, wax, different
plastics etc.) can give a too large measured value, since also light is
reflected by deeper layers
 Rapidly changing measuring conditions are likely to falsify the result
of measurement
2.4 Laser Classification
The LDM41A and the LDM42A are Class 2 laser product, ≤1 mW as stipulated
in EN60825-1:2007, Class 2.
Caution:
There is Class 2 Laser radiation. Do not stare into beam!
Figure 2 : Warning Sign Laser Radiation Class 2
The Laser power is limited to maximum 1 mW. The Laser radiation is visible. A
short-term exposure (duration up to 0.25 s) is harmless to the eye.
