Note
In the event that the air entrainment meter does not show the required
5 % or 10 %, check the initial pressure once again. If necessary
send the complete air entrainment meter back to the manufacturer
for checking.
16. After taking the reading, slowly open the right ball shut-off valve (B) to allow the
pressure to be released from the test pot.
17. Open the quick-release latches and take off the upper part of the air entrainment
meter.
18. Open the overflow valve by pressing the TEST button and allow the rest of the air to
flow out of the pressure chamber. The pressure-gauge pointer will now go back slowly
and will reach its initial position. See Section 7. Calibration instructions, image 4.
19. Remove the calibration tubes. Empty the test pot and whip out the air entrainment
meter until it is dry.
20. Your air entrainment meter is now re-calibrated and is ready for operation.
