SPAN CALIBRATION
(see our
YouTube
Channel for Calibration tutorial)
Calibra.:
Span calibration is undertaken to ensure accurate gas concentration
reading (i.e. ensure that the display reading is accurate and true). We
recommend calibration to be undertaken every 6 months. For analytical and
highly specific applications, calibration can be undertaken more often to ensure
the highest accuracy. If left beyond 6 months, the accuracy of the analyzer will be
compromised.
To undertake span calibration from the MENU SCREEN select Calibra. Expose
the analyzer to the calibration gas for 1 min. When using calibration gas bottles,
maintain a flow of at least 0.5L/min. Edit the gas concentration using left and
right buttons so the detector knows the concentration of the calibration gas.
After exposure, press EXIT. When complete, a blue floppy disk icon will be
displayed.
