ments. After loading factory setting, please calibrate the touch panel following the in-
structions in section 4.5, and load default settings following the above instructions.
5.7 Commissioning of the Analyzer
After completing the configuration, please verify the installation and setup of the analyz-
er with the following steps:
Check that the span calibration gas is connected before span calibration; and zero
calibration gas is connected before zero calibration. Calibration gases shall be con-
nected to the sensor without any leaking and in accordance with a good installation
practice. A leaking connection will result in loss of calibration gas and may result in
poor calibration. In order to have the accurate result, the pressure and flow rate of
the sample gas should be the same as the pressure and flow rate of the calibration
gasses.
Check that the setup of analog output signals is correct.
Check that the setup of alarm levels is correct.
Check that the setup of calibration values for zero and span calibration gas is correct.
Calibration can be performed when the indication of oxygen content on the Main Menu
has stabilized, normally about five minutes after starting the analyzer. Calibration is car-
ried out as described in the following chapter.
