2 Safety
2.1 Standards & Directives
To guarantee the safe operation of laser devices, all binding standards, directives
and instructions regarding laser safety and laser radiation protection must be
observed by manufacturers and users (refer to Declaration of Conformity).
The CHM 15k Cloud Height Meter is built and tested for compliance with
the following standards and directives:
1. Council Directive 2004/108/EEC
on the approximation of the laws of the Member States relating to
electromagnetic compatibility (EMC),
conforming to EN 61326 and EN 55011 standard requirements
2. Council Directive 2006/95/EEC
relating to electrical equipment designed for use within certain voltage lim-
its (73/23/EEC)
conforming to the following standards:
– EN 60825-1; Safety of laser products
– EN 61010-1; Safety requirements for electrical equipment for measure-
ment, control and laboratory use
In accordance with EN 60825-1:2007 and its inherent risk potential, the
CHM 15k qualifies as a class 1M laser device.
2.2 General Safety Measures
l
All safety notes in this User Manual, including any other applicable docu-
ments, must be duly observed and followed.
l
This User Manual must be kept within easy reach of personnel at all times.
l
The CHM 15k may only be operated with the inner door closed.
l
The CHM 15k Cloud Height Meter may not be powered by nominal volt-
ages other than 230 VAC.
2.3 Safety Notes Regarding the Laser System
There is invisible 1064-nm laser radiation emerging from the CHM 15k. It emits a
laser beam of very small divergence (< 0.5 mrad) and 90 mm beam diameter.
l
Do not directly look into the beam.
l
Avoid unnecessary exposure to invisible laser radiation.
l
It is strictly forbidden to use optical instruments, notably, field glasses, for
viewing the laser beam.
l
Class 1M laser radiation, if viewed over an extended period of time,
may cause damage to the eyes such as glare or irritation or even full
loss of eyesight.
l
Make sure the laser beam path is free from material with reflecting sur-
faces.
l
Follow all instructions especially those on emergence of laser radiation (also
