To prevent possible probe damage, be sure only the
sealed portion of the probe is immersed (see Fig. 10).
Put the probe tip into the water, avoiding the side or
bottom of the container. Wait for the readout to stabilize,
indicating the probe has reached the water temperature.
The readout should be —2°C to 2°C. There should be
ice remaining after the test to verify that inserting the
probe did not raise the water temperature.
