This thermometer is a precision instrument. Severe shock or strains may affect accuracy. Should calibration become necessary proceed as follows:
Fill a tall 32 oz. container with crushed ice, add cold tap water to fill the container and stir well. Immerse the thermometer to it's protective ring in the mixture, touching neither the sides or the bottom of the container. ALLOW A MINIMUM OF 30 MINUTES BEFORE ADJUSTING. Remove the thermometer from the container, hold the adjusting nut under the dial with a suitable tool and turn the dial so the pointer reads
32 degrees F.
