Test: Connect the tube of the tested channel to the pressure chamber. Press Ok to start inflating
the chamber and wait while the chamber inflates and deflates automatically and freeze takes place.
Pass/Fail: Pass for the inflation test is considered when the pressure inflates to 240 mmHg in less
then 10 seconds. Pass for the fast deflation test is defined as deflation to less then 15 mmHg in
less then 10 seconds.
Troubleshooting:
In case of failure of either test, one of the pneumatic elements: valves, pumps or internal tubes,
may be responsible for the failure. Follow the instructions in the section for leakage source
identification to pinpoint the source of failure.
4.6
Pressure Leakage Test
Objective: This test is designed to verify that the pressure chambers are not leaking.
Setup: Maintain the setup of the previous test.
Test: : Press Ok to inflate the chamber and wait until automatic freeze takes place. The chamber
will inflate to a set target pressure, and then hold the pressure for up to a minute, before pressure
release and auto freeze.
Pass/Fail: Pass is defined as a pressure drop of less then 3 mmHg over the course of the 20 second
test duration.
Troubleshooting:
In case of failure of this test, one of the pneumatic elements: valves, pumps or internal tubes, may
be leaking. Follow the instructions in the section for leakage source identification to pinpoint the
source of leakage.
4.7 Controlled
Deflate
RateTest
Objective: This test is designed to verify that the controlled deflate rate is accurate.
Setup: Maintain the setup of the previous test.
Test: : Press Ok to inflate the chamber and wait until automatic freeze takes place. The chamber
will inflate to a set target pressure, and then start deflating at a constant rate of 3 mmHg/sec until
automatic freeze.
Pass/Fail: Pass is defined as a deflate rate /- 1.5 mmHg/sec of the required rate.
Troubleshooting:
In case of failure of this test, one of the pneumatic elements: valves, pumps or internal tubes, may
be leaking. Follow the instructions in the section for leakage source identification to pinpoint the
source of leakage.
4.8
Automatic Check Valve Test
Objective: This test verifies that the check valves are opened at pressure of 300 mmHg +/- 20%.
