Casella CEL CEL-310 - Manual (Page 6)

The system is delivered with the Dose Badge configured for
either ISO or OSHA measurement. The user can change the configuration
by means of the Reader Unit, allowing the Dose Badge to be altered for
different Standards and Guidelines. A system may be founded with a
single Dose Badge and Reader, then expanded by adding further Dose
Badges and an appropriate number of chargers.
This manual describes the operation of the Dose Badge, Reader
Unit and Windshield.
1.1 The System
A Dose Badge system consists of a number of individual Dose Badges
controlled by a single Reader Unit. The Reader provides the method to
calibrate, start, stop and download measurements from a Dose Badge,
then download this information to a PC.
The system can be configured to measure according to ISO or
OSHA standards.
Those authorities who follow European Union measurement
procedures should use the ISO configuration. This satisfies the
requirements of IEC 61252 and employs the following settings.
Q = 3 Energy exchange rate,
80 dB Threshold level,
85 dB Criterion level,
8 hours Criterion time,
Freq. weighting A for all sound level measurements,
C for peak sound pressures,
Time weighting None.
Those authorities who follow U.S. measurement procedures
should use the OSHA configuration. This satisfies the requirements of
ANSI S1.25-1991 and employs the following settings.
Q = 5 Energy exchange rate,
80 dB Threshold level,
90 dB Criterion level,
8 hours Criterion time,
Freq. weighting A for all sound level measurements
C for peak sound pressures,
Time weighting Slow weighting.
