I have intermittent, rising or falling or incorrect HP sensor readings


If the High pressure Oxygen or Diluent sensors read very high or very low or jump around the sensors need to be replaced by Avon Underwater Systems Ltd. To complete a dive trip fit an analog High pressure gauge to the other HP port on the first stage for gas contents monitoring and turn off the HP sensor in DVO. Do not dive the Sentinel with no means of accurately monitoring HP readings!
