By pressing the “save” ( ) button in the main measurement screen, you store the current
measurement on the devices internal storage, using the measurement number indicated
above the battery indicator.
Some remarks about the RTA module:
• By definition, “max hold” and “EQ” are mutually exclusive settings.
• The elapsed measurement time is shown above the progress bar. If the
measurement interval is set to “continuous,” the measurement will run un-
til it is manually stopped. The progress bar itself is not used when measur-
ing continuously.
• Once saved, measurements can only be retrieved with the same frequency
resolution (i.e., a measurement carried out with 1/1 octaves cannot be re-
trieved as an 1/3 or 1/6 octave band spectrum).
• However, data recalled through the measurement browser are shown with
the frequency weightings selected at the time the measurement is recalled
- even if these are different from the settings that were in effect during the
measurement. This allows you to inspect the effect of frequency weightings
on all measurements saved previously
• Note that the spectrum and its corresponding broadband level are affected
by the same time- and frequency weightings. In other words, if the main
spectrum is A-weighted, then the level shown in the red field is also A-
weighed (and vice versa). If you wish to display a Z-weighted spectrum and
an A-weighted level at the same time, you need to display these in different
channels (main and aux).
• The measurement numbers form a separate consecutive series for each
module. That means that the same measurement number might occur
multiple times (once for each module; e.g. number #0002 might exist for
SPL as well as RTA, STIPA, etc.)
• The filters comply with the requirements of IEC-61260-1:2014 class 1 and
IEC-61260:1995 class 0.
