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).
