5.3 Reviewing the Calibration Settings

SoundAdvisor Model 831C
The following instances require you to enter unique correction values in the
Calibration Settings tab as shown in 5.3 Reviewing the Calibration Settings.
• Using a free-field microphone: For details, see the calibration data
shipped with calibrator.
• The calibrator and instrument are at a temperature other than room
temperature (23° C) or not near sea level. For details, see the
calibration data shipped with calibrator.
• Always recalibrate your meter when moving it to another location
(e.g. meter moved to or from 85 kPa static pressure elevation).
Step 1
On your 831C, go to Tools
When you perform a calibration using any preamplifier prelisted for the 831C,
the SoundAdvisor updates the saved calibration information for that
preamplifier. If you install a different preamplifier, the SoundAdvisor applies
the previously saved calibration information. As long as the same microphone
is being used with that preamplifier, the calibration is accurate.
Step 2
Choose an option from the Select Calibrator drop-down menu.
