AUTOMATIC ICE-POINT CALIBRATION
The DTK2 has an automatic ice-point calibration function. Please
follow these steps to calibrate your meter to the thermocouple
probes.
• ITEMS NEEDED:
1. DTK2 Thermometer
2. Two k-type probes
3. Crushed ice/water mixture
(distilled water recommended if available)
• CALIBRATION PROCEDURE
1. Connect both probes to the DTK2
2. Place probe tips in the crushed ice/water mixture
3. Power on the DTK2
4. Press and hold SET for five seconds.
a. The meter will enter ice-point calibration and 0.0°C will
flash on both T1 and T2 readings
5. Stir the ice bath with the probes submerged for one minute
6. Continue stirring the ice/water mixture until the readings
return to normal measurement (flashing will stop)
The ice-point calibration is now complete.
