Pressing the CAL key switches the M6200E 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 keys. Pressing either of these keys also puts the instrument into
multipoint calibration mode.
• The CALZ key is used to initiate a calibration of the zero point.
• The CALS key 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
Chapter 7 of this manual. Information related to performing For more information concerning the
zero/span, zero/span/shutoff and IZS valve options, see Section 5.4.
