The spot should always be smaller than the surface. The
smaller the surface, the closer the micro IR-100 should be to
the surface. For the best accuracy, the surface should be twice
as large as the spot.
Emissivity – Emissivity is a term use to describe energy emit-
ting characteristics of materials and has a value ranging from
0 to 1. The micro IR-100 uses a fixed emissivity of 0.95 to cal-
culate temperatures. This value is appropriate for the great ma-
jority of uses, including most painted surfaces.
Shiny or polished surfaces have a low emissivity and will give
inaccurate readings. One way to compensate for this is to apply
masking tape or flat black paint to the surface. Allow the tape
or paint to come to the same temperature as the surface and
measure the temperature of the tape or paint.
Temperature – While the micro IR-100 compensates for vari-
ation from ambient temperature, large changes in ambient and
measured temperatures can reduce accuracy. When signifi-
Do not direct the laser beam towards other people. Make sure
the laser is aimed above or below eye level. Laser beams may
be hazardous to the eyes.
Take appropriate precautions when working near electrical,
moving or hot parts. Close contact may cause electrical shock,
entanglement, burns and other serious injury. Protective equip-
ment may be required.
Set up and operate the infrared thermometer according to
these procedures to reduce the risk of injury or incorrect meas-
urements.
Set-Up
1. Check for an appropriate work area as indicated in the General
Safety Section.
2. Inspect the object being measured to and confirm that you have
correct equipment for the application. See the Specifications
section for range, accuracy and other information.
There are a variety of factors that can affect the accuracy of
the micro IR-100, including:
Field of view – The micro IR-100 uses two lasers to project
points on either side of the area to be measured. These points
indicate the approximate diameter of the area (the “Spot”) that
the temperature is being measured in. As the micro IR-100
moves further (D) away from the surface, that area and spot
size (S) increases. The area is approximately 0.05 times the
distance to the surface. (See Figure 7.)
