The sensing tip is a small indentation located about 1 inches from the end of the stem and must be fully inserted into the bird. The temperature should register in about 15-20 seconds. Wipe with a sanitizer after each use and before the next use. These are commonly found in the whole turkey and turkey breast. The pop-up thermometer device indicates the turkey has reached the final temperature for safety and doneness.
Experts suggest the temperature be verified with a conventional thermometer.
Ideally, these thermometers should be calibrated when first purchased as well as checked for accuracy before the holiday rush. Accuracy can be altered if the thermometer has been exposed to extreme temperature changes or has been dropped. There are two simple ways to test for accuracy. Place at least two inches of the thermometer stem into the cup, making sure the sensing tip is fully inserted. The tip should not touch the bottom or side of the cup.
