CEL-63x Environmental & Occupational Noise Meter

Casella CEL
This screen has the following options:
Own Logo
– This option prints a stored user logo before the report (see
later for details).
Octave L
eq
+ Max
– If narrowband results are stored this gives the
option to print the L
eq
and Max for each octave or 1/3-octave band.
Octave Ln’s
– If narrowband Ln‟s are stored and some Ln‟s are
currently selected this gives the option to print those Ln values for each
octave or 1/3-octave band.
Period 0010
–
0020 / 0075
– If the run stores two or more period
results then the user can select to print the results for up to 25 periods at
a time. In this example periods 10 to 20 are printed from the set of 75
period results stored.
Print Report
– When this option is selected, pressing the
key
prints the report. Pressing
Exit
or switching the printer off stops any
current printing.
The printed report includes the optional user logo; the run start date and
time and duration; and the instrument setup and calibration data. This is
followed by the cumulative or period broadband and narrowband results
and then by the Location, Operator and Signature fields which can be filled
in by the user.
NOTE
The functions printed in the report (and displayed on the results screens) are those that
are defined in the current measurement setup. The printing of octave and 1/3-octave
results can use considerable amounts of printer paper, especially if a number of
different periods are printed.
Up to five functions are printed for each set of frequency bands, so if Octave L
eq
+ Max
is enabled then selecting more than three Ln functions in the current measurement
setup will require two sets of frequency bands to be printed, using more paper.
Disabling both Octave options above just prints a broadband set of results.
Print Screens
This mode captures the current result screen and prints a graphical copy of this
screen to the printer.
While displaying the Memory results screen, select the View icon (instead of the
Printer icon) and use the keys to select each screen of the current runs results.
Press the
Run/Stop
key when you want to print the current screen.
This printing format is particularly useful when displaying octave or 1/3-octave
results when the graphical bar graph of the spectrum can be printed for any of
the selected narrow band functions.
