Setup:  Sequentially connect PVC0012 (PPG-DC Simulator Device) to each PPG channel.   

 

Test: : Press Ok to start the measurement and wait for automatic freeze.   

 

Pass/Fail: Pass is defined as DC reading of 21148 +/- 4.00 %..   
 
Troubleshooting:   
a)  In case of failure try replacing the internal PPG cable (PVC0057).   
b)  If failure persists, contact your authorized Viasonix service representative.   

 

4.12 PVR 

Test 

Objective: This test verifies the PVR performance of the pressure channels.   

 

Setup:  Place a digit cuff (PVB0075) on the index finger ans sequentially connect it to each 
pressure channel.   

 

Test: Press Ok to start PVR 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 relocating the digit cuff on the finger.   

b)

 

 If failure persists, try to fasten stronger the luer connector og the cuff to the respective tube.   

c)

 

If failure persists, try replacing the digit cuff (PVB0075).   

d)

 

If failure persists, contact your authorized Viasonix service representative.   

 

4.13 

Doppler Background Noise Test 

Objective: This test checks the Doppler background noise level.   

 

Setup:  Connect all Doppler probes to their respective connectors on the front panel.   

 

Test: Press Ok to start the measurement and wait until automatic freeze.   

 

Pass/Fail: Pass is definedcfor low background noise level of less then 2500 and voltage less then 
0.85, and current less then 1.75.   
 
Troubleshooting:   
a)

 

 In case of Failure, try replacing the respective Doppler probe.   

b)

 

If failure persists, contact your authorized Viasonix service representative.   

 

4.14 

Doppler Spectrum Test 

Objective: This test verifies the quality of the Doppler spectrum.   

 

Setup:  Connect all Doppler probes to their respective connectors on the front panel.
