4.2. Calibration Mode
Pressing the CAL button switches the analyzer into calibration mode. In this mode, the
user can calibrate the instrument 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.
 The CALZ button is used to initiate a calibration of the zero point.
 The CALS button is used to calibrate the span point of the analyzer. It is
recommended that this span calibration is performed at 80% 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 other sections of the manual:
 Section 9 details basic calibration and calibration check operations.
 Section 10 describes how to perform an EPA protocol calibration.

To avoid inadvertent adjustments to critical settings, activate calibration
security by enabling password protection in the SETUP – PASS menu
(5.5).
4.3. Setup Mode
The SETUP mode contains a variety of choices that are used to configure the analyzer’s
hardware and software features, perform diagnostic procedures, gather information on
the instrument’s performance and configure or access data from the internal data
acquisition system (DAS). For a visual representation of the software menu trees, refer
to Appendix A-1. Setup Mode is divided between Primary and Secondary Setup menus
and can be protected through password security.
4.3.1. Password Security
Setup Mode can be protected by password security through the SETUP>PASS menu
(Section 5.5) to prevent unauthorized or inadvertent configuration adjustments.
