secondary sensor, blue tip for the third sensor. The setpoint scale rotates such that
the current setpoint value is always below the red arrow marker at the top and always
pointing up towards the red arrow marker on the top. This means that when the
setpoint is changed the setpoint scale will rotate to reect the change. This will help
the diver to quickly understand if the pp
