CEL-63x Environmental & Occupational Noise Meter
85 Casella CEL
Output Periods:-
This gives the option to Output Period Results or not (see below).
1/1 Octave,
1/3 Octave L
eq
If the meter is a „B‟ or „C‟ variant and Output Period results is
selected this allows a period L
eq
of each octave or 1/3 octave
frequency to be output with the period results.
Online Mode:-
This enables or disables Online mode.
NOTE
Online Mode will ONLY operate when the Meter is in Periodic mode. (i.e. Periodic
mode is set in the Measurement Control- Data Sets Menu). If Cumulative mode is
selected then Online Mode will be ignored as if it had been disabled.
Results Output:-
Normal Results Output:-
All Results lines are output in ASCII and are terminated with a carriage return
and then linefeed character.
The general output format is
<line type>,YYYY-MM-DD,HH:MM:SS,descriptor1,value1,descriptor2,value2..
CRLF
Where CRLF is the 2 characters Carriage return (ASCII 13) followed by line feed
(ASCII 10) .
Normal Profile Result (output every 1 second to 1 hour):-
This outputs 1 line of results to RS232 every profile interval. These are the same
profile results which are stored on SD card and can be output to Casella insight.
This outputs the 6 fixed functions L
Aeq
, L
AIeq
, L
AFmax
, L
ASMax
, L
AImax
and L
Cpeak
. If
the Profile time is set to 1 minute or more and the Profile functions Ln option is
selected and the meter is a CEL-633A/B/C then the 6 fixed functions are
followed by 5 Ln values using the current Z, C or A weighting. These are always
Fast time weighted so if the Current broadband weighting is „C‟ then L
CF10
, L
CF50
,
L
CF90
, L
CF95
, L
CFnn.n
are output (where nn.n is the user selected Ln percentile).
If Ln‟s are not output then 6 functions are output in a single line e.g.
