Section 1 Introduction - Cirrus Research doseBadge CR:112A User Manual

Section 1 Introduction

Thank you for purchasing the doseBadge Personal Noise Dosimeter System from Cirrus
Research plc.
This manual describes the operation of the CR:112A and CR:112AIS doseBadge units
and RC:112A doseBadge Reader.
The measurements provided by these two versions of the doseBadge are identical. The
only difference between the units is that CR:112AIS version carries an MSHA Intrinsic
Safety Certification.
The doseBadge is a unique solution to the problems associated with the measurement
of Personal Noise Exposure. The doseBadge 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 doseBadge to a Reader unit via an infra-red
link which removes the need for keys or controls on the instrument.
The CR:112A & CR:112AIS doseBadge and RC:112A Reader Unit, when used with the
dBLink3 software, provide Dual Threshold Measurements.
The configuration of the two channels is as follows:
Parameter
Exchange Rate (Q)
Criterion Time
Criterion Level
Threshold
Time Weighting
A system can be started with a single doseBadge and a Reader unit, and expanded by
purchasing additional doseBadges and the appropriate number of charging units. A
range of additional external charging units allow a system to be expanded simply and
easily without any of the components becoming obsolete.
Also described are the optional RC:101A Keyfob Remote Control and the UA:100
Windshield. The Keyfob allows the doseBadge to be started and stopped without the
RC:112A unit, and should be ordered separately.
