This morning I just found something unusual with my cat eye V3N HR sensor, when I put the data to Max it’s show 240 bpm , which it’s very impossible, when I move with bike , the heart rate value on computer keep blinking , it’s seem never happen before.

When I came home I test the HR sensor , I put it beside the computer and I am not wear the HR sensor, on computer it should be display 0 bpm but it was not, it display kind random value and some time max to 240 bpm LoL.

I reset all data , remove HR sensor and computer battery with no result. Just try to googling and found the problem , HR strap was moist  :)) , I washed the HR strap an put it under the sun and  it work again like charm.
