Teledyne API - T100 UV Fluorescence SO2 Analyzer Overview of Operating Modes

4.2. CALIBRATION MODE
In this mode the user can, in conjunction with introducing of zero or span gases of
known concentrations into the analyzer, cause it to adjust and recalculate the slope
(gain) and offset of the its measurement range. This mode is also used to check the
current calibration status of the instrument.
For more information about setting up and performing standard calibration
operations or checks, see Section 9.
For more information
about setting up and performing EPAPressing the CAL button,
switches the T400 into calibration mode.
If the instrument includes one of the available zero/span valve options, the SAMPLE
mode display will also include CALZ and CALS buttons. Pressing either of these
buttons also puts the instrument into calibration mode.
The CALZ button is used to initiate a calibration of the analyzer’s zero point using
internally generated zero air.
The CALS button is used to calibrate the span point of the analyzer’s current
reporting range using internally generated O
3
span gas.
For more information concerning calibration valve options, see Section 3.6.
For information on using the automatic calibrations feature (ACAL) in conjunction
with the one of the calibration valve options, see Sections 9.3.3 and 9.4.
Note It is recommended that this span calibration be performed at 90% of full
scale of the analyzer’s currently selected reporting range.
EXAMPLES:
If the reporting range is set for 0 to 500 ppb, an appropriate span point
would be 450 ppb.
If the of the reporting range is set for 0 to 1000 ppb, an appropriate
span point would be 900 ppb.
