Sound Level Meters – User Manual
4. Operations in more detail
Please note: from this chapter on, the manual describes capabilities which are
available on different models within the Optimus range. This includes the
CR:16XX and CR:17XX GPS-enabled instruments.
If you are unsure which capabilities your instrument has, you can check by looking at the general
view/page 5 (and 6 on some models).
4.1 NoiseTools
All GPS sound level meters can be used with the licence-free NoiseTools software,
which can be used to configure the instrument (some options are only configurable within
NoiseTools and not on the instrument – it will be made clear in the text where this is the case).
NoiseTools is also a powerful platform for storing, analysing and organising your data, and can
produce reports for publication. VoiceTag notes and audio recordings can only be played back
through NoiseTools.
4.2 Keypad and controls
Your sound level meter is controlled via the four arrow keys (up, down, left and right), centre
select key and three soft keys. The soft keys change their function depending on the mode that
the instrument is in. The soft key function is shown above the button on the display.
The left and right keys move between the views and the up and down keys move between the
pages of each view.
The function of the centre button varies depending on the screen being viewed, and duplicates
one of the soft keys. Its function includes ‘menu’, ‘select’, ‘OK’ and ‘exit review’ of measurements.
