Figure 8.6 Test Luna
Test pressure channels and solid state catheters
The easiest way to test the Luna and the catheters (solid state or air charged)
is by using a water-column of at least 100 cm.
The procedure is as follows:

Connect the catheter(s) to the connectors on the Luna.

Click the Zero button to zero all channels at atmospheric pressure
simultaneously. (You can also zero the individual channels by clicking the 0
button behind the pressure channels.)

Lower the catheter to 100 cm below the water surface of the water-column.
The pressures measured by the transducers are now shown in the window
as a value and as a horizontal bar. The readout on the screen should be
100 cmH
2
O. The maximum deviation may be 2 cmH
2
O plus the error of the
pressure transducers at 100 cmH
2
O, in accordance
to the manufacturer’s
specifications. Check if the channels display the correct pressure.
