6. Start calibration by selecting Start Cal .
7. Read pressure from the Test Device and Give correct reference pressure to calibration point 1
(100
×
kPa).
8. Disconnect the high pressure test adapter from the central outlet and the A-WGU.
9. Reconnect the O
2
and Air pipeline pressure to the A-WGU (leave the N
2
O pipeline pressure
disconnected from the ADU).
10. Set the O
2
flow control to 1 l/min.
11. Open the N
2
O flow control to depressurize the pressure.
12. Check that the N
2
O flow indicate 0.0 on the ADU display.
13. Give reference pressure 0.0 to calibration point 2 (100xkPa).
14. Wait until ‘Calibration OK’ or ‘Failed’ is displayed.
15. Save the calibration by selection
Save CAL. To abort calibration, select Abort CAL .
16. Reconnect the N
2
O pipeline pressure to the ADU.
17. Select Previous Menu . Perform the needed calibrations according to the calibration tree.
