7 TECHNICAL SPECIFICATION

7.1 Specification

Sound Exposure Meter/Dosimeter Standards:

IEC 61252: 2002, BS EN 61252: 1997, ANSI S1.25 - 1992 for

dosimeters and sound exposure meters.

The CEL-35X conforms to the requirements for EMC emissions

and immunity as specified in IEC 61000-4-2/6-1, 61000-4-6/6-2,

61000-4-3/CISPR 61000-6-3.

Electromagnetic and electrostatic compatibility:

The CEL-35X was tested with a pink noise acoustic source of

85dB and complies with the immunity requirements of clause 15

(IEC 61252). No additional devices are connected during normal

use.

There is no degradation in performance or loss of functionality

following the application of electrostatic discharges.

All settings and orientations of the instrument have similar radio-

frequency emissions. These radio-frequency emissions are within

the specified limits of this standard.

All modes of operation have similar immunity to power and radio

frequency fields.
