4.3. CALIBRATION MODE
Pressing the CAL button switches the T360 into multi-point calibration mode. In
this mode, the user can calibrate the instrument or check the instruments
calibration with the use of calibrated zero or span gases.
If the instrument includes either the zero/span valve option or IZS option, the
display will also include
CALZ and CALS buttons. Pressing either of these
buttons also puts the instrument into multipoint calibration mode.

CALZ is used to initiate a calibration of the zero point.

CALS is used to calibrate the span point of the analyzer. It is recommended
that this span calibration is performed at 90% of full scale of the analyzer’s
currently selected reporting range.
Because of their critical importance and complexity, calibration operations are
described in detail in Section 5 of this manual. For more information concerning
the valve options, see Section 3.6.
