SoundTrack
LxT - Time History
With
the optional Data Logging
firmware installed, when in the
Time History mode the SoundTrack
LxT can automatically log up to
16 acoustic and non-acoustic
parameters, at time intervals
from 1 second to 24 hours. The
control of the time intervals is
achieved via the following 6 Run
Control modes of the instrument:
-
Manual Stop:
initiated and stopped manually
-
Timed Stop:
initiated manually and
automatically stopped after a
user-defined period.
-
Stop
When Stable:
initiated manually and
automatically stopped after a
user-defined period and when the
measured level has remained
within a user-defines band.
-
Continuous:
initiated and stopped manually
as in the Manual Stop mode. The
exception being that the
Continuous mode has a
user-selected capability of a 24
hour, user time set, auto-store.
-
Single Block Timer:
initiated and stopped manually,
when measurement have been made
in the time interval defined by
the single block timer.
-
Daily Timer:
initiated and stopped manually,
when measurement have been made
during the separate time blocks
defined in the instrument setup.
The
16 measurement parameters are:
-
RMS
Levels:
Leq; Lmax; Lmin (with predefined
A/C/Z frequency weightings and
Slow/Fast/Impulse detectors)
-
Peak
Level:
Lpeak (with predefined A/C/Z
frequency weighting)
-
Specialized Acoustic Parameters:
- LAFTM5
Tacktmaximal 5 (used in Germany)
- Ltwa1 and Ltwa2
time-weighted averages
(associated with
Dose 1and Dose 2 exchange rates and
thresholds for
Dosimeters 1 & 2
- LCSeq - LASeq
- OBA 1/1 Leq
- OBA 1/1 Lmax
- OBA 1/1 Lmin
- OBA 1/3 Leq
- OBA 1/3 Lmax
- OBA 1/3 Lmin
- Battery Level
- Internal Temperature
