Select a Casella 633 Data Set before making a

measurement. The Casella 633 can collect two data sets:

Cumulative Measurements

A cumulative measurement is simply a single set of results from an entire noise testing measurement duration.

Periodic Measurements

A periodic measurement is a series of measurements and results that are recorded at the end of separate fixed intervals.  Therefore, there a group of results as opposed to one measurement result.

1-2. Use the Arrow keys and press the B key to select the Settings menu.

3-4.  Likewise, use the Arrow keys and press the B key to select the Measurement Control menu.

5-6. Again, use the Arrow keys and select the Data Sets Menu.

7-8. In the Data Sets Menu,  use the arrow keys to move between the Measurement Mode, Profile Interval, and the Event Profile Interval.

The Cumulative Data Set does not record Time History Information unless you include a Profile Recording.

A Profile Recording simultaneously records a series of quick measurements during a Cumulative Measurement.  The Profile Recording supports LAeq, LAIeq, LCpk, LAFmax, LASmax, LAImax, and optional Ln% statistics (Broadband Fast A-weighted Lns only) functions.

When you use profile recording, you can set the interval of each of the profile measurements to one of the following: OFF 100ms, 1, 2, 5, 10, 15, 20, 30 or 60 seconds 2, 5, 10, 15, 20, 30 or 60 minutes.

To select a Periodic Measurement Data Set

To select the Periodic Data Set, set the Measurement Mode to Periodic. Next, select the Periodic Interval to one of the following settings: 1, 2, 5, 10, 15, 20, 30 or 60 minutes 2, 4, 6, 8, 12 or 24 hours. The Periodic Interval is the set amount of time for each sound level meter recording.


Synchronize Time

The Synchronize Time Option pairs either the Periodic or Profile times to the actual time. As an example, if a Periodic Data Set has a Periodic Interval of 1 hour and a run begins at 10:08am, the run will end at 11:00am and run intervals for each subsequent whole hour. If the Synchronize Time Option is disabled, the data will run from 10:08am to 11:08am and so on.

You can also synchronize runs by using the timers, by starting and ending runs on whole time period intervals. This synchronizes both the periodic and the profile measurements.
