Measurement Settings
For a detailed description of the
settings defined on this tab, refer to
the instrument’s user manual.
The settings available on the Measurement sub-tab define
some basic sound level parameters such as Frequency and
Peak Weighting, Detector type, Integration Method, Ln
percentages, as well as OBA (Octave Band Analyzer)
settings such as Range, Bandwidth, Weighting, and
Spectrum as shown in FIGURE 3-8.
Octave Band Data
Note that the OBA settings will only be available if the
appropriate optional firmware has been installed:
• Model 831: 831-OB3 (1/1 and 1/3 octaves)
• SoundTrack LxT: LxT-OB1 (1/1 octave only) or LxTOB3 (1/1 and 1/3 octaves)
Dosimeter Settings
In order to measure noise dose, the
Model 831 must have the optional
firmware 831-IH loaded. This
functionality is standard with the
SoundTrack LxT.
The settings defining the measurement of noise dose are set
from the Dosimeter sub-tab, shown in FIGURE 3-9.
Predefined Setups
The Dosimeter settings can be loaded from a set of
Standards based pre-defined criteria by clicking the Load
Std. Criteria button which will display the Standard Dose
Criteria dialog as shown in FIGURE 3-10. Simply highlight
the desired Standard and click OK to automatically populate
the settings.
Measurement Control Settings
For a detailed description of the
measurement control settings, with
and without time history, refer to the
instrument’s user manual.
The settings available on the Measurement Control sub-tab,
as shown in FIGURE 3-11, will define how and when the
instrument will RUN, STOP and/or STORE data when
taking a measurement and if a Measurement History will be
kept. Most of the settings on this tab are shown/hidden and/
or enabled/disabled based primarily on the Run Mode
setting and the Enable Measurement History setting.
Measurement History
If an FST Period is selected on the
Time History sub-tab, the Enable
Measurement History setting will be
disabled.
SLM Utility-G3 Manual
The Enable Measurement History setting determines if a
measurement history will be saved and stored with each
Measurement. Of the remaining settings on this sub-tab,
only "Interval Time Sync." and "Interval Time" are
dependent on this setting.
