IR Measurements

Taking Measurements

Point the meter toward the object being measured, then press and
hold the MEASURE button. The meter will turn ON and take a reading.
Read the measured temperature on the LCD. The meter turns off
automatically approximately 8 seconds after the MEASURE button is
released.

While pressing the MEASURE button:

Press the LASER button to turn on the laser pointer.

Press the MAX button to display and hold the highest reading. The
display will update with each higher reading.

The object being measured should be larger than the spot size as
illustrated in the distance to spot diagram.

Measurement considerations: 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 raise to improve
the accuracy of the measurement.
