VMA340 Pulse sensor false data

I have been doing a VMA340 Heart rate/Pulse sensor as my school work.
I have the example codes tested them but i get over 230bpm only. tested many other thresholds but it keeps giving me the same data

Would be very helpful if anyone who have done something with the VMA340 sensor and knows how i can get the right data out of it

Please post a full sketch that you have a problem with following the advice given in
