Section 1 Introduction
Thank you for purchasing the Personal Noise Dosemeter System from Pulsar
Instruments plc.
The dosemeter is a unique solution to the problems associated with the measurement
of Personal Noise Exposure.
The dosemeter itself has no controls or cables which means that the unit can be used in
situations where the wearer is working in confined spaces or where there is a risk of a
cable being caught in machinery.
Measurements are downloaded from the dosemeter to a Reader unit via an infra-red
link which removes the need for keys or controls on the instrument.
This version of the dosemeter, the MODEL 22 and the MODEL 22R Reader Unit, provide
a range of configuration options which allow the system to be used to measure and
record noise levels to most Occupational Noise and Industrial Hygiene Regulations.
The MODEL 22 dosemeter and MODEL 22R Reader Unit, when used with the Pulsar
AnalyzerPlus software, provide Dual Channel Measurements.
Channel 1 can be configured to be any combination of the Exchange Rate (Q), Criterion
Level (CL), Criterion Time (CT), Threshold (TH) and Time Weighting (TW). Channel 2 is
preset to a 3dB ISO configuration as shown below:
Parameter
Configuration Options
Channel 1
Channel 2

3dB, 4dB or 5dB
3dB
Criterion Time

85dB
Threshold

, 85dB
or 90dB
None
Time Weighting
None
All of these configuration options can be selected from the MODEL 22R Reader Unit. In
addition, the Pulsar AnalyzerPlus software allows user defined configurations to be
loaded into the Reader Unit. The software includes preset configurations such as ISO,
OSHA, ACGIH and US ACHPPM.
A system can be started with a single dosemeter and a Reader unit, and expanded by
purchasing additional dosemeters and the appropriate number of charging units.
This manual describes the operation of the MODEL 22 dosemeter unit and MODEL 22R
dosemeter Reader.
Also described are the optional RK1 Keyfob Remote Control and the WS22 Windshield.
The Keyfob allows the dosemeter to be started and stopped without the MODEL 22R
unit and should be ordered separately.
