Using the Data Display
T
he 831C takes a measurement, and simultaneously displays the resulting data a series of
themed tabs, such as the Live tab, Overall tab, etc. At a minimum, tabs and pages display the
following SLM metrics:
•
Real time sound metrics
•
Frequency of sound at each octave
•
L
eq
, L
S
, L
PEAK
of the overall or live sound
•
Fast and Impulse detectors
•
Temperature, GPS, and elevation of the measured sound
•
The current sound, weighted for specific values
This module shows how to navigate and view SLM data, and how to adjust or customize
the data display to fit your requirements.
In this module:

4.1.1 Understanding the Live Tab
•
4.1.2 Understanding the Overall Tab
•
4.1.3 Viewing Weather Related Data

4.1.1 Understanding the Live Tab
When the 831C is powered on, the Live tab is the first display. Since the values on the Live
tab show active, real-time values the meter is currently sensing, this page is not controlled
by the Run/Pause button. The Live tab allows you to view the current SPL (sound pressure
level) without disrupting your measured data.
Press the
up
8
or
down
2
buttons to scroll up or down on the pages of the Live tab.
The labels for sound metrics on the 831C are designated by international standards. For
many displayed values, the frequency and time weighting are indicated in the name of the
metric. For example, L
AS
is the A-weighted sound pressure level measured using the Slow
detector.
