Calibrate Thermometer

This fast, easy procedure offers added daily assurance of exacting temperature measurement:

1. Fill a container with finely crushed ice, top with clean tap water and stir well.
2. Remove the thermometer from its case and slide the stem through the hole in the wrench pocket (no additional tools required) until the adjusting nut below the dial head snaps securely in place.
3. Using the case as a handle, immerse the thermometer stem into the ice a minimum of 2 inches for 30 seconds. The stem should not touch the sides/bottom of the container.
4. If the temperature reading is 32°F (0°C), the thermometer is accurately calibrated.
5. If adjustment is required, turn the head of the thermometer while the stem remains immersed in the ice, until the pointer reads 32°F.
