Maintenance
9.3.5 Global system view
This option allows you check various components of the instrument:
• O2 calibration valve
• Gas calibration valve
• Reference volume valve
• Main purge valve
• Needle purge valve
• On-off valves function
• Regulating valves function
• Ultrasound
• Flow regulation
• Manual displacement
• Proportional valve
Check a component by pressing on the button/schematic (which will turn to green) and observe
the values being displayed.
Note: If the gas flow rate is manually changed, be aware that the automatic purge procedure (every 5
minutes) will reset the gas flow rate back to 0.25 mL/s, which will have an impact on the values being
observed.

Selecting this option initiates the standard system startup process, without having to power the
instrument off and on. See
Instrument startup on page 30 for more information on system
startup.

due date based on how the service has been configured.
