high resistance to damage. Data integrity is further protected by a dose
microphone lead which is designed to resist knocks and abrasions
without affecting the signal passing from microphone to instrument.
Both instruments can be operated and deliver dose and SLM
results without the need for other equipment, beyond an acoustic
calibrator. However, they become even more versatile when their
measurement and setup data is transferred via a PC using the CEL-6702
dB10 or CEL-6704 dB12 Windows™ based software.
These programs enable the instruments to be fully configured.
Dose (DATA) setups can be added or removed from the instrument,
while the individual measurement parameters can be added, deleted or
changed in a setup. Some setup parameters, such as measurement
range, can either be set to a particular value or left to the user to change
via the instrument keypad.
dB10 and dB12 have the facilities expected of fully featured 32
bit Windows

packages, enabling report production with cut and paste
between applications and comprehensive word processing capabilities.
In addition, dB12 has extensive on screen graphing facilities.
4.1 Sound Level Meter & Intrinsically Safe (IS) Models
Both dosimeters can be converted to a miniature sound level meter by
fitting a CEL-425 SLM Microphone Adaptor. The CEL-320 becomes a
CEL-320S Sound Level Meter,
while the CEL-360 becomes a
CEL-360S Logging Sound Level
Meter.
For sound level meter
operation refer to Section 7.
Intrinsically safe versions
are available of both dosimeter
and sound level meter models.
The part numbers have “/IS” after their standard part number. The
model line up is shown in Table 1.
4.2 CEL-320/320S Noise Dosimeters
The following features apply to the CEL-320 and CEL-320S. These
instruments are ideal for quick on-site surveys and for monitoring
personal noise exposure in accordance with European ISO or USA
OSHA, MSHA, DOD and ACGIH standards.
For dose measurement, they are passive instruments with
settings that may be reviewed by key strokes, but which can be selected
only by means of the dB10 or dB12 software.
