Measurement considerations
The object being measured should be larger than the spot size as
illustrated in the distance to spot diagram.
If the surface of an object to be measured is covered with frost, dust or
other materials, surface cleaning must be performed before accurate
measurements can be made. High Reflective Surfaces: If the
surface of an object to be measured is highly reflective with a very low
emissivity value, apply masking tape or apply flat black paint to the
surface to improve the accuracy of the measurement.
Battery Replacement
A flashing battery icon on the display indicates that the battery which
powers the meter has weakened. Open the battery compartment on the
rear of the meter, replace the battery and close the compartment.
