I use the VR3 with my Dolphin. I must admit it took awhile to get everything working OK. First and foremost do you have NEW O2 cell? Having more than one cell is a good idea. My early problems were do to bad cells. When you calibrate with air the output of the cell should be between 9mV - 13mV. I typically see about 10mV. Make sure there is no corrosion / discoloration on the connector. If so clean the connections and try again. I just came back from a week long diving trip where the VR3 with Dolphin worked flawlessly.

Regards,

Steve
