Information covered in these sections relates to operations that are vital to

Calibration of the dosemeter
The dosemeter should be calibrated before each measurement. It is also 
possible to carry out a second calibration check at the end of the 
measurement before the data is downloaded. 
Please refer to Appendix 3 dosemeter Calibration on page 63 for details of the 
recommended calibration procedure for the dosemeter. 
dosemeter Configuration
The MODEL 22 dosemeter can be configured to meet the requirements of 
many different Occupational Noise and Industrial Hygiene Regulations and 
Guidelines.  
The Dual Channel capability allows the dosemeter to be used, for example, where there 
is a requirement to measure noise exposure in accordance with both OSHA and ISO 
standards. 
Please ensure that the MODEL 22R Reader Unit is configured for the correct functions 
and parameters before making measurements with the dosemeter.  
The Pulsar AnalyzerPlus software can also be used to configure the dosemeter and 
Reader unit to meet these requirements. 
dosemeter Battery Performance
The NiMH rechargeable battery within the MODEL 22 dosemeter is designed to 
be recharged using the supplied battery chargers. Do not attempt to charge 
the dosemeter battery by any other means. 
Before the first use 
Before the dosemeters are used for the first time ensure that the units are 
allowed to fully charge which may take up to 3 hours.
