Overview
CE compliant products bear the “CE” mark and include a
Declaration of Conformity
stating the
particular specifications and conditions that apply. The test records and supporting documentation
that validate the compliance are kept on file at the factory.
This product meets the essential requirements of applicable European directives, as amended for
CE markings in accordance with the product family standard for:
•
electrical equipment for measurement, control, and laboratory use
•
immunity requirements for equipment used in controlled EM environments
Refer to this product’s Declaration of Conformity (DoC) for any additional regulatory compliance
information. To obtain the DoC for this product, visit

The electromagnetic compatibility (EMC) directives specify two basic requirements:
1.
The device must not interfere with radio or telecommunications.
2.
The device must be immune from electromagnetic interference from RF transmitters, etc.
The standards are published in the
Official Journal of European Union
under direction of CENELEC
(European Committee for Electrotechnical Standardization). The specific standards relevant to data
acquisition equipment are listed on the product’s
Declaration of Conformity
.
The safety standard that applies to data acquisition products is EN 61010-1 : 1993 (
Safety Requirements
