CO2-HRV-PPG study
Connect the CO2-absorbing syringe  directly to the capno.
Bring up CapnoCalibrator [it is really not a calibrator. It is a Zeo-Reset utility].
RUN the program for at lest 10 minutes to allow it to really warm up.
Bring up Calibrate, then Zero Calibration from the TOP MENU.
This will bring up the 'Reset CO2 Zero' window.
Click the Reset Button in the Window.
That's it!
