Boreal Laser Inc. GasFinder2 Operation Manual — Appendices July 17th 2017
Appendix G — Calibration
The GasFinder2 is shipped already calibrated and does not require any calibration in the fi eld.
The calibration of the GasFinder2 is done
by passing a known concentration of gas
through a test cell, which is placed in the
path of the laser beam.
The calibration data are stored in the
instrument’s software as a standard
reference waveform.
During operation, the GasFinder2’s internal reference cell is compared with this stored
waveform at frequent intervals. Any signifi cant deviation generates a status code to alert the
user to a potential calibration problem. The
GasFinder2 software can be used to check the
reference cell, as well as to download sample, reference, and calibration waveforms (System
Menus/Internal Arrays Transfer) to verify that the internal calibration system is functioning
correctly. If
GasViewOP is being used, these waveforms can be displayed on the computer
(Port1/Arrays Plot Enable and press the ‘Arrays Transfer’ in the GasFinder2 menu)
.
A technical note detailing the calibration procedure and quality assurance is available from
