CEL-63x Environmental Noise Meter

36 Casella CEL

When the instrument has cycled through all six timers, it either stops the run

sequence or, if the Repeat option is enabled, it repeats the sequence

continuously from the beginning.

The timers can be set to run on a specific day of the week at a specific time

(7-day timer), or to start on any day of the week at a specific time (24-hour

timer).

The start time for a timer can be the same as the end time for the previous timer

so that, unlike some meters, the CEL-63x does NOT require a number of

seconds when noise is not measured between runs to perform housekeeping

operations.

Data sets

The measurement data sets option sets how the CEL-63x

instrument captures measurements over a period of time.

You can set the instrument to capture measurements during a

single run. These are called cumulative measurements.

You can set the instrument to capture repeated measurements to

create a periodic time history.

Figure 11. Cumulative measurements and Periodic Time History

Figure 11 shows three examples of cumulative measurement runs and periodic

time histories.

1. This example is a single cumulative measurement run as a dark blue

line. The duration of the run is set by the Measurement start and stop

modes. You can use the screens in the Memory results to see the

captured measurements as a graph or as values. The measurements are

stored in memory and can be transferred to a computer by USB.
