Field Calibration Procedures

1. The PDT300 is only calibratable in a slush ice solution (60% crushed ice and 40% tap water) or a water bath. Do not attempt to calibrate in any other manner

2. Immerse the stem of the thermometer to at least 1/2 length in the slush ice solution

3. Wait for the reading to become stable (usually ±2° of 32°F or ±1° of 0°C)

4. Press and hold the D-H button for 8 seconds to begin calibration

5. CAL will be displayed for two seconds and calibration at 32°F/0°C is completed

6. Remove the thermometer from the ice water and continue to take measurements

Note: CAL will be displayed any time the D-H key is pressed for 8 seconds, but the thermometer will not be re-calibrated unless the tip is inserted in ice water
