2. Test step
(almost empty bottle)
1. Set argon flow to: 2 l/min
2. Close the bottle valve.
3. Press the COAG pedal on the footswitch. The display on the pressure
regulator manometer should clearly fall. If the input pressure is too
low, the test specimen must automatically cancel activation and dis-
play a vacuum message.
4. Call up the bottle fill level window again. The fill level display (%)
must have fallen to around zero.
