8. Dose Testing and Datalogging
8.1 Overview
The dosimeter noise survey and datalogging functions operate at the same time. For example, while
the %dose and TWA (time weighted average) values are being calculated and displayed (for the
dose meter’s noise survey) individual SPL readings are being stored by the datalogger.
Noise surveys and logged data are stored in ‘RUNS’ which are memory locations (1 to 20). Note that
the meter can collect up to 14,400 readings total, spread out over the 20 RUN memory locations. The
‘RUN’ parameter is located in the DATA menu. The DATA Mode Menu table and a Screen-Shot
section are provided directly after the instructional text below:
8.2 Running the Dose Meter Noise Survey and Datalogger
1. Use the supplied software program (recommended) to configure the meter’s noise survey and
datalogging parameters (a software User Guide is provided on the supplied CD-ROM), or
manually configure the meter following the instructions provided in the SETUP and OPTION
mode sections of this guide. For compliance, the noise survey parameters must match the
requirements of the regulation/standard in question.
2. In the SETUP mode (or using the supplied software) set the Criterion Level, Exchange Rate,
Threshold, Frequency Weighting, Response time, Range, and Peak parameters. Note that if a
configuration has already been stored, it can be recalled in the SETUP mode. Reference Section
11.3 for SETUP Mode details.
3. In the OPTION mode (or using supplied software) set the Date/Time, Test Duration, Test Begin
(BEG) time, Test End time, Sample rate (logging period), Repeat, Pair, and Timer functions.
Reference Section 11.5 for OPTION Mode details.
Note: for an 8 hour Dose noise survey the minimum Sample rate is 2 seconds.
4. For the entirety of the test, the microphone should be clipped to the test person’s lapel and the
meter should be clipped to the test person’s belt.
5. To run the dosimeter/datalogger the meter must be in the DATA Mode of operation. Press the
Menu button to select the DATA Mode (if not already selected).
TIMER Notes
:
•
The Timer setting is critical for determining whether the test begins immediately (Timer OFF)
or at a programmed time (Timer ON).
•
With the TIMER set to OFF, recording can begin immediately by pressing the RUN/PAUSE
button. When the meter is recording, the REC icon will appear solid and the DATA icon will
flash.
•
With the TIMER set to ON, and with the Beginning and End times programmed, after
RUN/PAUSE is pressed recording will NOT start until the programmed Begin (BEG) time is
reached. The REC icon will be flashing (indicating that the meter is in “standby” waiting for
the Begin time); the DATA icon will be on solid.
•
Up to 5 Begin/End times can be pre-set and tests can be programmed up to 30 days in
advance.
