Model 831 Data Displays
The Instrument Software supports
the organization and display of the measurement
data such that the interpretation of measurement
data is a logical and simple task for the
end-user. The software provides multiple display
choices by the use of simultaneous measurement
parameters for frequency weightings and detector
selection. The Data Displays show the following
basic SLM measurements:
(1) Bar
Graph display showing 1second Leq data over the
last 120seconds
(2) Leq
Numeric Value for selected frequency weighting
(A/C/Z) and 1 second integration time
(3)
User Selected SLM Parameters
(4)
Measurement Elapsed Time
The Data Display options consist
of:
(1) Live Display Page, where the
displayed measurements are always active,
real-time data. The selectable SLM parameters
consist of:
Leq: with selectable A/C/Z
frequency weighting;
Instantaneous RMS Levels (L): with selectable
Slow/Fast/Impulse detectors and A/C/Z selectable
frequency weighting;
Peak Levels: with selectable A/C/Z
frequency weighting;
(2) Overall Display Page, where
the displayed measurements are averaged over the
elapsed measurements time, consisting of:
Leq: with selectable A/C/Z
frequency weighting;
Peak Levels: with selectable A/C/Z
frequency weighting;
Max and Min RMS Levels: occurring during
the measurement period;
(3) Any Level displays of all
possible selections/combinations of frequency
weighting and detector selection during Live and
Overall displays.
