4.3. CALIBRATION MODE
Pressing the CAL button switches the T101 into multi-point calibration mode. In this
mode, the user can calibrate the instrument or check the instrument’s 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.
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 Section 6 of this manual.
4.3.1. CALIBRATION PASSWORD SECURITY
The T101 calibration functions may be password protected for to prevent inadvertent
adjustments. When the calibration password has been enabled using the PASS menu item
found under the Setup Menu (Section 4.4.5), the system will prompt the user for a
password anytime CAL,
CALZ, CALS activated.
