PRM2103 Reference Manual Performing Calibration Checks B-9
TAKE NOTE
The standard check
level is set by performing a
manual Cal. Check directly
after performing an acoustic
calibration.
FIGURE B-9 Cal. Check Tab
The Standard Cal. Level field holds the last saved cal check value. The
default value is 94.00 dB.
You can manually change the dB level by navigating to the field and
changing the number value.
After performing the calibration check, the Model 831 displays a message
prompting you to save a new Standard Cal. Level, if needed, as shown in
Figure B-10.
TAKE NOTE
Answer Yes to save
the Standard Cal. Level value.
This should be done
immediately following the first
calibration check. Otherwise,
answer No to simply record the
level (and spectrum) in the
Calibration Check History for
trend determination.
