Maintenance tasks
PHASEIN Gas Master can be used to complete the maintenance task.
Leak test
1. Connect Nomoline to the ISA gas analyzer, with the analyzer connected to
PHASEIN Gas Master.
2. Tightly block the gas inlet of the Nomoline sampling line.
The cuvette pressure (“Atm press - Cuvette press [kPa]” in PHASEIN Gas Master)
will start to rapidly decrease, until the internal pump stops when the cuvette
pressure is decreased to about 15 kPa below atmospheric pressure.
3. When the internal pump stops, quickly block the exhaust port tightly.
When blocked, the cuvette pressure shall be 15 - 23 kPa below atmospheric
pressure.
4. Stop the pump by sending parameter “Stop pump” under “Installation &
maintenance” in PHASEIN Gas Master.
5. Wait about 10 seconds until the cuvette pressure value as shown by the PHASEIN
Gas Master is stable. Note the value.
6. Wait an additional 10 seconds.
7. Check that the cuvette pressure value has not changed more than 3 kPa in 10
seconds.
