… Description of menus and parameters
The line position must be within the acceptance window marked
by the two vertical red lines. For some instruments such as dual
gas instruments more than one absorption line is plotted.
With the <Reload> button the second harmonics signal is
updated. The data can be saved to file (<Save to file>) for later
analysis.
This is equivalent to the function <Download readings> in the
“File download/upload” menu, see
on page 65. The scale of the axes is
modified by clicking on the axes labels.
It is possible to open a previously saved signal and scale it to
compare with existing signal. Two curves are shown for each
signal.
Log readings <Custom logging>
With <Custom Logging> all data displayed in the Measurements
menu can be logged to an ASCII file at specified regular intervals.
Figure 38: Menu ‘Custom Logging’
The sampling period (logging interval), file directory, and the
filename are user defined (default filename is
“gmYYMMDD.log”).
If <New file at midnight> is selected the program will create a
new logging file at every midnight with the default filename
reflecting the new date.
Before logging <Select Parameters> should be pressed and the
parameters of interest should be marked.
The selected parameters are automatically arranged in columns
in the logging file.
The first column is always seconds after the last midnight (PC
time) and the last two columns are always the instrument status
(-4 (sleep mode)/ -1 (startup)/ 0 (ok)/ 1 (warning)/ 2 (error)) and
the measurement mode (0 (ok)/ 1 (zero)/ 2 (span)).
Parameters can be added to or deleted from the logging file
without interrupting the logging process. The configuration of
the logging file may be modified (e.g. specify text qualifier, data
separator, add comment on top etc.).
