TPI 310C FIELD CALIBRATION
Fill a plastic or metal container with crushed ice and add clean water to a depth of at least 4 inches. Stir the ice
and water for 2 to 3 minutes prior to performing calibration to ensure the water is completely chilled. Make
certain there is plenty of ice in the mixture and always use clean water. Distilled water works well. The
temperature of an ice bath is approximately 32°F (0°C).
Insert the stainless steel shaft of the 310C into the ice bath making sure at least one inch of the tip is immersed.
Allow the reading on the thermometer to stabilize.
Note: The temperature reading must be within 23°F to 41°F (-5°C to 5°C) for calibration to have effect.
