The flowmeter should indicate 0.5 to 0.7 L/min.
4. Rotate the flow control counterclockwise (increase). The ball should rise
immediately after rotation is begun. It should rise smoothly and steadily
with continued counterclockwise rotation. When a desired flow is set, the
ball should maintain in a steady position.
5. Rotate the flow control clockwise to minimum flow.
6. Press the Alternate O

1. Open the O
2. Rotate the flow control clockwise (decrease) to shut off the flow. The ball
should rest at the bottom of the flow tube and not move.
3. Rotate the flow control counterclockwise (increase). The ball should rise
immediately after rotation is begun. It should rise smoothly and steadily
with continued counterclockwise rotation. When a desired flow is set, the
ball should maintain in a steady position.
4. Occlude the auxiliary O
flow tube and not move. A ball that does not rest at the bottom of the flow
tube indicates a leak and requires service.
5. Rotate the flow control clockwise to shut off the flow.
The gauge needle should come to rest within the zero range bracket when no
suction is being supplied. Gauges which do not comply may be out of
calibration.
1. Adjust the regulator setting to minimum.
2. Turn the mode selector to I (On).
3. Ensure the gauge remains less than 200 mmHg (26 kPa, 0.26 Bar).
4. Occlude the inlet.
5. Ensure the gauge remains less than 200 mmHg (26 kPa, 0.26 Bar).
6. Adjust the regulator in an increasing vacuum level.
7. The gauge should rise after rotation has begun. The gauge should rise with
continued rotation of the regulator adjustment.
8. Adjust the regulator setting to minimum.
9. Turn the Mode selector to O (Off).
