3.3 Select Measurement Setup
(Factory- or User-Prepared Setups)
The Setup specifies the particular parameters that are to be measured.
Selection procedures for broadband and narrow band measurements are
similar, although a wider choice of parameters is available for broadband,
while the range of frequency bands displayed can be restriced for narrow
band.
One factory configured setup and up to four user defined setups
can be stored for each available bandwidth.
Measurements can be made at specified time intervals with
storage of period noise data and exceedance (L n ) values and profiles.
Display screens that are available only for a CEL-490 are shown with a
dashed
- - - - line.
3.3.1 Select Broadband Measurement Setup
The factory setup for broadband measurement contains a set of standard
parameters selected for general purpose use.
User setups contain parameters that have been selected to
perform some particular task and are saved under a user setup identity.
Changes to user setups are saved for re-use, however any changes to
the factory setup will be lost and the standard settings offered each time
the instrument is re-started.
Select and save broadband setups as follows.
