optimus sound level meter user manual
Page 9
This allows you to record notes and information before a measurement by simply
speaking into the microphone, then play them back later in the NoiseTools software.
You can save time when making measurements, and remove the need to carry a
notepad and store any important information about your measurements
.
A single measurement range
By using the very latest in digital technology combined with 40 years’ experience in
designing sound level meters, we have given the
optimus instruments the ability to
measure from 20dB(A) to 140dB(A) and up to 143dB(C) Peak in a single span.
This means that there is no need for you to choose which range you may need for
your measurement, and that there is almost no chance of the instrument overloading
or under-ranging.
A clear, simple display of the information you need
The display used on the
optimus
is a high resolution colour OLED type. This gives a
clear, bright display that is easy to read in all light conditions as well as allowing us to
use colour to show specific functions and information.
All of the information that you need is shown clearly on the screen with the most
useful function, for example the Leq in the Leq View, shown in large white text. This
makes it easy for you to see the information that is important at a glance.
A modular design to future proof your investment
The optimus instruments are based around a modular design which allows you to
upgrade and update your instrument if and when the time arises.
This means that your instrument will meet your current and future needs, no matter
what you need to measure.
Audio Recording during measurements
The
optimus
green instruments can record and store audio data (the actual sounds
heard by the microphone) during a measurement.
This data can be downloaded along with the noise measurements for analysis and
review and can be used to identify the source of the noise.
Audio recordings can be started either manually or automatically using a set of
triggering rules.
