system
.bak
System History Back-Up
A back-up of historical
log of
conguration changes
System Conguration History - When the system.his le
exceeds 100KB size the contents is saved to this .bak le
and the .his le is emptied. This .bak le is in the form of
ASCII data les that can be opened with Microsoft
“Notepad” as simple .txt le formats. The content can then
be copied and pasted into Microsoft Excel spread. Each
conguration change is logged with the date (MM-DD-YYYY)
and time that it occurred, the parameter (e.g. opl) and the
new value. Also, whenever the analyzer is started-up or shut-
down the ‘TruePeak Open/Close” parameter will be
logged.
Example:
11-20-2006 08:13:10 opl(inch) 39.96 43.31
11-20-2006 08:13:26 temperature(F) 509.0 86.0
11-20-2006 08:13:40 pressure(psi) 14.50 14.50
valspe .his
Validation Spectra
All spectra captured
during On-Line and
Off-Line Validations
Spectra captured for historical Validations (On-Line and
Off-Line) are stored in this le.
valspe .bak
Validation Spectra Back-
Up
Backed-up spectra captured
during On-Line and Off-Line
Validations
When the valspe.his le exceeds 1MB size the contents is
saved to this .bak le and the .his le is emptied. This .bak
le is Spectra captured for historical Validations (On-Line and
Off-Line) are stored in this le.
zero00 .spe
Zero Calibration Spectra
Absorption Spectrum and
coefcients at time of cali-
bration
This le is essential to the analyzer calibration - if
this le does not exist or is corrupted, modied or
otherwise tampered with then the analyzer calibration is
invalid. It contains essential information relating to the
Zero Calibration of the analyzer.

.spe
Historical Zero
Calibration Spectra
Previous Absorption
Spectrum and coefcients at
time of previous
calibrations
zero01 through zero09 are previous les with zero01
being the most recent. The most recent previous
zero01 can be restored in the analyzer as ‘Previous
Calibration’. The factory calibration which can also be
restored in the analyzer is named zero10.
system .las
System Laser
At the time of current down-
load
Laser related parameters for production, service and
troubleshooting, including:
Serial Number of module
Laser temperature
Ambient T-Comp curves
Thermister parameters
Laser drive current parameters
Laser temperature out of range Fault settings
Laser driver resistor (R18 for VCSEL, R76 DFB)
