• Visual Field. Make sure that the area where the temperature is to be measured is larger than
the.diameter.of.the.laser.beam..The.smaller.such.an.area,.the.more.necessary.it.is.to.be.closer.
to it. When accuracy is in doubt, make sure the area in question is at least twice as large as the
diameter.of.the.laser.beam.
• Distance & Diameter of the Laser Beam. Gradually as the distance (D) increases between the
thermometer and the object whose temperature measurement is desired, the diameter of the laser
beam (S), or the area of measurement becomes larger. See: Fig: 1.
• Looking for the hottest point.To look for the point of the object with the highest temperature,
carry.out.different.measurements.moving.the.thermometer.before.the.outside.of.the.area.involved,.
then on all of the surface of the object, with a movement from high to low.
• Usage Limitations
1 The thermometer is not adapted to carry out measurements on reflective or shining surfaces (
stainless.steel,.aluminum,.etc.).See.the.paragraph.relating.to.Emissivity
2 The.instrument.cannot.measure.through.transparent.surfaces.such.as.glass:.the.value.indicated.
should.indeed.be.that.of.the.temperature.of.the.glass.
3 Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the temperature
reading.
