Z For this menu item the pressure chamber must not be in the pump
head.
Z Select menu level L0.
Z The nominal pressure and actual pressure displays read the current
pressure values detected by the pressure sensors. The two readings
must be '115' (2).
If this is not the case, adjust the two readings to '115' (2) by means
of potentiometers P1 and P2 on the AM3--UNI PCB.
Z After readjustment of the zero points calibrate menu items L1 -- L3.
Z Press the start / stop button to exit menu level L0.
Z Place the flexible test tube set into the pump head.
Z Select menu level L1.
Z Select a nominal pressure of 200 mm Hg (MC).
Z Generate a pressure of 200 mm Hg (267 mbar) externally.
Z Adjust the nominal pressure and actual pressure readings to the same
value.
0.5
Z The instrument display reads a digital value.
Z If the values are the same, press the start / stop button in order to exit
menu level L1.
Z Remove the flexible test tube set.
Z Select menu level L2.
Z The device will automatically look for the motor offset voltage.
Z When the 'L' in the nominal flow display blinks, the check is completed.
You may now select a new menu level.
Z Place a genuine tubing set into the pump head. This test will be perfor-
med without fluid delivery.
Z Select menu level L3.
Z The pump roller wheel turns. The nominal pressure display reads the
rotations per minute (rpm).
Z Potentiometer P3 on the AM3--UNI PCB must be adjusted in such a
way that a speed of 355
rpm (5) is acchieved.
Z This menu item cannot be exited by means of the start / stop button.
Switch off the device with the mains/power switch.
