Calibration History Back-Up
A back-up of historical log of analyzer
calibrations
Calibration History - When the calibr.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 Calibration and/or Validation event is logged with the date
(MM-DD-YYYY) and time that it occurred, the Mode (Calibration
or Validation), the specific type (Transmission Calibration, Zero
Calibration, etc.) and the ‘K’ (constant) factor used for the event
Example:
11-14-2007 14:11:19 span_calibrate 612814.89 9250.84
152665.88
11-14-2007 14:50:16 transmission_cal 14.95

capability.
span00 .spe
Span Calibration Spectra
Absorption Spectrum and coefficients
at time of calibration
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 Span Calibration of the analyzer.

Historical Span Calibration
Spectra
Previous Absorption Spectrum
and coefficients at time of previous
calibrations
span01 through span09 are previous files with span01 being the
most recent. The most recent previous span01 can be restored
in the analyzer as ‘Previous Calibration’. The factory calibration
which can also be restored in the analyzer is named span10.
system .cfg
System Configuration
All essential analyzer & installation
specific parameters required by the
analyzer for the given application &
installation
This file is essential to the analyzer - if this file does not exist
or is corrupted, modified or otherwise tampered with then
the analyzer cannot function. It contains analyzer specific
parameters relating to every detail of the measurement,
calibrations, compensation factors, I/O configurations, Valve
control configurations, signal processing, etc. This file is used by
FACTORY PERSONNEL ONLY to evaluate if the configuration is
appropriate for the analyzers intended use.

System History
A historical log of configuration
changes
System Configuration History - 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
