When the cook time ends, turn off the pressure cooker. Let the pressure release naturally for 10 minutes, and finish with a quick pressure release. When the valve drops, carefully remove the lid. Use an instant-read thermometer to check that the cheesecake has reached 150°F in the center. If not, relock the lid and cook the cheesecake at High Pressure for 5 minutes more, followed by another 10-minute natural pressure release.
