I think tou are misreading your gauges.
The high pressure gauge tells you the pressure inside the CO2 tank, and will almost always read exactly the same until just before your tank goes dry. I saved some money and bought a regulator without this gauge as it is pretty useless to me - once the tank is almost dry and that gauge starts to drop, you need to refill pretty quick. Since I can get a refill at a local fire extinguisher service shop 7 days a week, this is a useless indicator for me.
The other gauge does NOT tell you the pressure of your "canister" (did you mean your keg?). It tells you the pressure you have your regulator set at. It will provide a reading, if the tank is open, whether you have it hooked to a keg or not.
