4.2 Recommendations before Operating
• If the measured surface target diameter is less than 2"/50mm Ø, then
place the sensor as close as possible to the target surface (<20"/50cm
away). See Field of View (FOV) information under Specifications.
• If the target surface is covered with frost or any matter, clean it before
taking a measurement.
• If the target surface is highly reflective put some matte tape, or matte
paint, over it before measuring.
• If the thermometer is erratic, or seems not to be measuring properly,
make sure that the sensor is clean and not covered by condensation.
