Setup: Maintain the setup of the previous test.
Test: : Press Ok to inflate all chambers and wait until automatic freeze takes place. The chamber
will inflate to a set target pressure, and then deflate quickly until automatic freeze. In case the
tested check valve does not meet the required criteria after the first inflation session, the test is
automatically repeated for up to 4 more times.
Pass/Fail: Pass is defined as pressure chamber is between 275 and 315 mmHg. If the pressure is
greater than 315 mmHg, proceed with manual measurements with the external pressure sensor,
since the limits of the internal pressure sensor are reached.
Troubleshooting:
In case of pressure above 315 mmHg, proceed to perform the manual check valve test.
4.9 Manual Check Valve Test
Objective: This test verifies that the check valves are opened at pressure of 300 mmHg +/- 20%,
and is performed only if the automatic test shows pressures higher then 315 mmHg.
Setup: Maintain the setup of the previous test, but turn on the external pressure device.
Test: : Press Ok to inflate the tested pressure channel. Wait until a window opens and type in the
respective field the pressure from the external device. Press Ok to complete the test.
Pass/Fail: Pass is defined as pressure chamber is between 275 and 350 mmHg.
Troubleshooting:
In case of pressure above 350 mmHg, the check valve needs to be replaced.
4.10 PPG AC Test
Objective: This test verifies the AC performance of the PPG sensors.
Setup
: Connect each PPG sensor to the respective PPG channel and perform a PPG measurement
on the same index finger.
Test: : Press Ok to start the PPG measurement and press freeze after several seconds of signal
acquisition.
Pass/Fail: Pass is defined when a smooth and oscillatory signal is obtained. If this criteria is not
met, press the FAIL button on the right.
Troubleshooting:
a) In case of Failure, try replacing the PPG sensor (PVC0075).
b) If failure persists, try replacing the internal PPG cable (PVC0057).
c) If failure persists, contact your authorized Viasonix service representative.
4.11 PPG DC Test
Objective
: This test verifies the DC performance of the PPG sensors.
