Casella CEL CEL-310 - Manual (Page 5)

1. INTRODUCTION
The CEL-310 Dose Badge is a unique solution to problems associated
with the measurement of personal noise exposure. It is controlled and
downloads data via infrared signals and in consequence needs no
external controls or cables. This allows it to be used in situations where
the wearer is working in confined spaces, or where there is a risk of
cables becoming caught in machinery.
The Dose Badge can be configured to make measurements
according to ISO or OSHA standard, where it provides the following
information.
Run time Duration of the measurement,
L AEq / L AVG Average sound pressure level during the
measurement period,
L EP,d / TWA Daily personal noise exposure,
% Dose Noise exposure as a percentage of a preset
total,
