Getting to know your
optimus
– features and capabilities
The
optimus
instruments are designed around a modular structure that allows an
instrument to be upgraded and updated with new capabilities (functions), protecting
your investment for the future.
To check which capabilities your
optimus
has, go to General View / page 5 (and 6 on
some models). This will list all the available capabilities. Alternatively, a Feature Matrix
is available on the Cirrus Research website, which lists all the capabilities for all
optimus
models.
Some options cannot be changed while the
optimus
is measuring, and a message will
appear on the screen telling you ‘cannot be changed while measuring’. Some menu
choices are disabled while measuring, and will appear grey on the screen.
Views
The views are accessed by pressing the left and right control keys. The views are
available when the
optimus
is measuring, not measuring or in review mode, but the
pages available in each mode will differ.
Not measuring
When not measuring, the information shown is live, instantaneous values.
Measuring
When measuring, these live values are still shown, but you are also shown
cumulative overall values for the current measurement period.
Review Mode
In review mode, the values shown are the overall cumulative values for the
meaurement.
General View
This shows the status of the instrument with the calibration data, the capabilities that
are fitted, serial numbers of the instrument, microphone and preamplifier along with
details of the standards that the instrument meets.
Sound Level View
This view shows the Sound Pressure Level or SPL, with the maximum and minimum
sound level (Lmax and Lmin) with a choice of A, C and Z frequency weightings.
