4.3. CALIBRATION MODE
4.3.1. CALIBRATION FUNCTIONS
Pressing the CAL key switches the 9110TH/M 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 the zero/span valve 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 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.
4.4. 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 instruments performance and configure or access data from the internal data
acquisition system (DAS). The areas access under the Setup mode are:
