This Type 1 meter is ideal for most environmental and community
noise measurement, industrial noise
surveys, and many other applications such as occupational "noise
at work" assessments.
The noise measurement process usually consists of:
Checking the meter's calibration. This is important for any
measurements that may be used for legal purposes.
Making the measurements, either manual or automatic, repeating
measurements.
Viewing the noise measurement results.
Presenting reports.
Checking the Calibration
Fit the calibrator onto the microphone as shown opposite.
Switch the Calibrator on.
Select Calibrate in the menu and press OK.
The meter will automatically check its calibration and make
any adjustments. If there are any major problems with the
meter or microphone capsule it will report an error.
The results of the calibration are stored and can be viewed
on the display or downloaded using the software provided.
Making a Basic Noise Measurement
Position the microphone.
Select a suitable measurement range using the key.
Press the key
to start the measurement.
To finish the measurement press the key.
The results of the measurement can be read from the display.
The measurement is automatically stored so that it can be
viewed again later or it can be downloaded to the software.
Making Automatic Timed Measurements
The Sound Level Meter can be set to make automatic and
repeating noise measurements. To make long measurements
easier the meter can be mounted on a standard camera tripod
(option CT1).
Using the menu options, set the measurement time (e.g.
15 minutes).
Select the Repeat option to make multiple
noise measurements.
Press the key
to start the meter running.
The Sound Level Meter will now make repeating measurements,
automatically storing each one. The resulting measurements
can be viewed later on screen or downloaded to a computer
using the software supplied.
Viewing the Noise Measurements
The noise measurements can be viewed on the meter's display
or you can connect the meter to a computer and download
them using the software and cable that are included.
The Deaf Defier software can store the results for further
analysis and present various noise reports. For more information
please visit the software web page.
