    Digital Thermometer

    Anyone know how to re-calibrate a digital thermometer? A few days ago it started saying my water was 120*+. I guess I better get to looking for a new one before closing time comes. Good thing is I am not close to closing. We got up to 100* today.

    Most thermometers are recalibrated at 32 in ice water or 212 in boiling water. The question is how to change what the reading is. If you know how to change the number then stick it in a bowl of ice water and change the number to 32.

    If in direct sunlight it could misread. Also, check batteries. Electronic do strange things when running with bad power.
