system .bak
System History Back-Up
A back-up of historical
log of
configuration changes
System Configuration History - When the system.his file
exceeds 100KB size the contents is saved to this .bak file
and the .his file is emptied. This .bak file is in the form of
ASCII data files that can be opened with Microsoft
“Notepad” as simple .txt file formats. The content can then
be copied and pasted into Microsoft Excel spread. Each
configuration 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 file.
valspe .bak Validation Spectra Back-
Up
Backed-up spectra captured
during On-Line and Off-Line
Validations When the valspe.his file exceeds 1MB size the contents is
saved to this .bak file and the .his file is emptied. This .bak
file is Spectra captured for historical Validations (On-Line and
Off-Line) are stored in this file.
zero00 .spe Zero Calibration Spectra
Absorption Spectrum and
coefficients at time of cali-
bration This file is essential to the analyzer calibration - if
this file does not exist or is corrupted, modified or
otherwise tampered with then the analyzer calibration is
invalid. It contains essential information relating to the
Zero Calibration of the analyzer.

Calibration Spectra
Previous Absorption
Spectrum and coefficients at
time of previous
calibrations zero01 through zero09 are previous files 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)
