How to Check If Your Digital Cooking Thermometer Is Working Properly
- 1). Fill a bowl with ice and just enough water to cover the ice. Stir.
- 2). Place the needle of the thermometer in the water. After few seconds the thermometer should read 32 F. If it doesn't, you may need to calibrate the thermometer.
- 3). Find the calibration screw on the back of your thermometer while it is still immersed in the water. Turn the screw with the screwdriver until it reads 32 F.
