1. Connect a multimeter across the Pins
4
&
9 of the terminal
marked RS 232 to check continuity.
2. Verify that with normal operation of unit and (no alarm
conditions exist) the pins show discontinuity (open contact).
3.
Create an alarm condition.Verify that in an alarm condition the
pins show continuity (close contact).
29. PROXIMAL
1.
Pinch the proximal tubing connected to the proximal inlet.
2. Verify that the pressure in the proximal circuit rises and the
manometer reads
a
pressure of 30
-
60 cm.H20.
3.
If the pressure is not within the specified range, clean out or
replace restrictors
RES206 and RES122 in the proximal circuit.
(Refer to figure 2.7, pneumatic diagram)
1. Connect
a
standard Oxygen Analyzer at the main flow side of
the unit.
2. Remove reservoir bag and plug the outlet for the reservoir bag.
3. Set the unit to spontaneous mode.
4.
Adjust the spontaneous flow to
10
LPM.
5.
Set the F102 at .21 and note F102 read by the analyzer.
6. Repeat step
5
for F102 settings of
.3,
.6, .9,and 1
.O.
7.
Verify that the F102 read is within tolerance range.
