optimus sound level meter user manual

Operations in more detail
Please note: from this chapter on, the manual describes capabilities
which are available on different models within the
optimus range.
If you are unsure which capabilities your
optimus
has, you can check
on the instrument by looking at the General View / page 5 (and 6 on
some models), or look at the Features Matrix available on the Cirrus Research website:
www.cirrusresearch.co.uk/optimus/library
NoiseTools
All optimus instruments are delivered with a copy of the 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 environment for storing, analysing and organising your
data, and produces reports for publication. VoiceTag notes and audio recordings can
only be played back through NoiseTools.
Keypad and Controls
The optimus is controlled via the four arrow keys (up, down, left and right) and three
soft keys, which change in function depending upon 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 ambient light sensor on the front of the instrument will illuminate the keypad and
adjust the brightness of the display automatically when the light level falls.
When the pause function has been activated (described on page 27), the right soft key
toggles between pause and stop. Press once to pause/back erase and twice to stop, or
alternatively press and hold for three seconds to stop.
