Guide
Use a leave-in thermometer throughout cooking only when it is designed for that job. Use an instant-read thermometer for brief checks near the expected finish.
Leave-in probes are made to monitor during cooking. Instant-read thermometers are inserted for a reading and then removed.
Aim for the thickest relevant portion and avoid bone, gristle, the cooking surface, and large pockets of fat.
For burgers, chops, and thin cuts, inserting from the side can place more of the sensing area in the center.
Large or irregular foods can heat unevenly. Verify additional areas rather than trusting a single point.
Clean the probe as directed to avoid transferring contamination, and keep non-waterproof electronics dry.
Common questions
Do so for an oven-safe leave-in probe. For an instant-read model, check near the expected finish and remove it after reading.

Yes, especially in large, whole, stuffed, or irregular foods where temperature may vary.
