If the pressure readings are incorrect then calibrate the pressure control as described below.
Calibration
1.4 If the pressure readings are incorrect then calibrate the pressure control as follows:
1.4.1 Turn the pressure control knob to the minimum setting.
1.4.2 Using a small, flat bladed screwdriver, carefully remove the pressure control knob. Be
careful not to move the arbour.
1.4.3 Rotate the screw in the centre of the pressure control arbour (counter-clockwise to
increase) until the indicated pressure is as specified in Table 33.
Note : Ensure that the pressure control arbour does not move.
1.4.4 Carefully replace the pressure control knob, ensuring that the control knob rotation is
limited between the minimum setting and the stop pin (if fitted).
1.4.5 Check the indicated pressure at minimum and maximum settings (Refer to Table 32)
and readjust if necessary.
1.4.6 Variation between the ports is to be no greater than 4 mmHg.
1.4.7 Attach the flow meter tube to whichever outlet is the duty port and check the free flow
again. The flow readings should be as specified in Table 31. Variation between the
ports is to be no greater than 1 litre/minute.
