Sprinkle the brown sugar over the ham so that it covers as much ham as possible.
Place lid back onto your cooker to close and make sure the pressure gauge is closed.
Set your cooker to high pressure and cook for 8 minutes.
Let the pressure naturally release. You can also press the quick release button, just make sure there is a dish towel nearby to help with any excess steam.
You can strain the extra jus in the pot and serve it alongside your ham as a gravy.
