Measurement Considerations

If the surface to be measured is small (13 mm (1/2 in.) or less), hold the probe as close as possible to the surface (no more than 50 mm (2 in.) away).

If the surface to be measured is covered by frost or other material, clean it to expose the surface.

If the surface to be measured is highly reflective such as polished metal, apply masking tape or a matte finish paint to the surface.

If the probe seems to be giving incorrect readings check the front of the probe. There may be condensation or debris obstructing the sensor; clean per instructions in the maintenance section.

Quick Check

For a quick check of the probe, point it directly at ice immersed in water (slush), the meter should read, within specifications limits, 32°F (see Accuracy specifications).
