    – enhanced time profile
lets you select the functions to be measured as a func-
tion of time. Select from -weighted functions as well as
- or -weighted – even -weighted peak! Furthermore,
enhanced profile opens up for the use of source coding
– see Adding markers for details. Apart from this there is
no difference between basic and enhanced time profile
mode.
Selecting which functions to log
We always recommend that you keep the number of
functions to measure as small as possible. is helps to
maintain the overview and keeps the amount of memory
spent low. Although it may be tempting to measure “eve-
rything”, do not forget that you are going to review the
acquired data afterwards. How much time are you willing
to devote to that?
Setting up the functions to log:
1
To gain access to the profile function activation menu,
press  > 3 [() .] . is menu looks as shown
to the right.
2
Navigate in the menu as usual and use the  and
 keys to activate the functions required for your
task. Deactivate those that you won’t need. A 1 means
activated and a 0 means deactivated.
3
Both the -weighted and the - or -weighted func-
tions are accessible from within this menu. Use the
 key to switch between - and - or -weighted
(which is set up in the 2nd network menu – see Simple
sound measurements for more on this.
