RIDGID micro IR-200 Manual De Instrucciones página 11

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-200, including:
Field of view – The micro IR-200 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-200
moves further (D) away from the surface, that area and spot
size (S) increases. The area is approximately
tance to the surface. (See Figure 7.)

The spot should always be smaller than the surface. The smaller
the surface, the closer the micro IR-200 should be to the sur-
face. 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-200 allows adjustment of the emissivity value
from 0.10 to 1.00 to calculate temperatures. If the emissive prop-
erty of a surface is unknown, an emissivity of 0.95 can be ap-
propriate for many applications, such as painted surfaces.
Values of emissivity for common materials are included in Fig-
ure 8.
