Appendix 1 Specifications
The MODEL 22 Personal Noise Dosemeter and the MODEL 22R Reader Unit have been
designed to meet the requirements of IEC 61252:1993 Personal Sound Exposure Meters
and the ANSI S1.25:1991 Personal Noise Dosemeters. The MODEL 22 dosemeter and
the MODEL 22R Reader unit must be used as a combination to ensure compliance with
these standards.

Measurement Functions:
The MODEL 22 dosemeter and MODEL 22R Reader Unit support Dual Channel
measurements. The measurement data is divided into three sections. In all situations
the Overall Measurement Data is stored.
If the dosemeter is configured with Channel 1 and Channel 2 having identical
parameters, the Pulsar AnalyzerPlus software will only display Channel 1.
