2. Safety
Safety Notes
Before operating the device, you must read, understand, and follow all instructions,
dangers, warnings, cautions, and notes.
FLIR Systems reserves the right to discontinue models, parts or accessories, and other
items, or to change specifications at any time without prior notice.
Remove the batteries if the device is to be stored for an extended period.
Warning Statements
Do not operate the device if you do not have the correct knowledge. Incorrect operation
of the device can cause damage, shock, injury or death to persons.
Do not start a measuring procedure before you have set the function switch to the
correct position. Failure to do so can cause damage to the instrument and can cause
injury to persons.
Do not change to the resistance mode when measuring voltage. This can cause damage
to the instrument and can cause injury to persons.
Do not measure the current on a circuit when the voltage increases to more than 1000 V.
This can cause damage to the instrument and can cause injury to persons.
You must disconnect the test leads from the circuit under test before you change the
range. Failure to observe this warning can damage the instrument and cause bodily
injury.
Do not replace the batteries before you remove the test leads. This can cause damage to
the instrument and can cause injury to persons.
Do not use the device if the test leads and/or the device show signs of damage. Injury to
persons can occur.
Be careful performing measurements if the voltages are > 25 VAC rms or 35 VDC. There is
a risk of shock from these voltages. Injury to persons can occur.
Do not do diode, resistance or continuity tests before you have removed the power from
capacitors and other devices under test. Injury to persons can occur.
Be careful when performing voltage checks on electrical outlets. These checks are
difficult because of the uncertainty of the connection to the recessed electrical contacts.
You must not rely solely on this this device when determining if the terminals are not
“live”. There is a risk of electrical shock. Injury to person can occur.
Do not touch expired/damaged batteries without gloves. Injury to persons can occur.
Do not cause a short circuit of the batteries. This can cause damage to the instrument
and can cause injury to persons.
Do not put the batteries into a fire. Injury to persons can occur.
Use extreme caution when the laser pointer is on.
Do not point the beam toward anyone's eye or allow the beam to strike the eye from a
reflective surface.
Do not use the laser near explosive gases or in other potentially explosive areas.
Refer to the CAUTION statement label (shown below) for critical safety information.

8. Thermal Imaging
8.1 Thermal Imager Basics
In the Thermal Imaging mode, the user can measure a
targeted surface’s temperature by detecting the energy
emitted by the surface under test. Color variations
reflect temperature variations. See Section 11.3,
Infrared Energy and Thermal Imaging Overview for in-
depth information. The laser pointer and display cross
hairs assist in targeting.
Press the IGM button to open the Thermal Imager. In
Fig 8-1 the meter is set to color palette IRON. Select
other palettes in the Thermal Settings Menu (refer to
Section 8.3, Thermal Settings Menu).
Fig. 8-1 Thermal Image Example

8.2 Thermal Imager Operation
To customize the Thermal Imager, refer to Section 8.3, Thermal Settings Menu. For
basic operation, follow these steps:
1. Set the function switch to any position.
2. Press the IGM button to switch the Thermal Imager ON. Point the thermal
imaging lens (back of meter) toward an area to test.
3. The display will show the temperature in the upper left hand corner for the
targeted area.
4. In the Thermal Imaging mode, use the laser pointer and display cross hairs for
targeting. These can be switched ON or OFF in the Thermal Settings Menu.
5. In the Thermal imaging mode, the meter continues to operate normally as a
Clamp Meter. Note that in the Thermal Imaging mode, view clamp
measurements and function on the left side of the display. If desired, the
meter can be set to image-only mode in the Image Mode menu, see Section
8.4, Image Mode Menu.
6. The Distance to Spot ratio for the imager is 30:1 meaning that the
measurement spot is 30 times smaller than the distance from meter to spot
(at a distance of 30”, the meter ‘sees’ a target spot of 1”). See Fig. 8-2.
7. The thermal imager’s FOV (Field of View) is 50 degrees (side view) and 38.6
degrees (top view) see Fig. 8-3 (a) and (b).

11.3 Infrared Energy and Thermal Imaging Overview
A thermal imager generates an image based on temperature differences. In a thermal image, the
hottest item in the scene appears as white and the coldest item as black. All other items are
represented as a gray scale value between white and black. The CM275 also offers color images
to simulate hot (lighter colors) and cold (darker colors) temperatures.
It may take some time to get used to the thermal imagery. Having a basic understanding of the
differences between thermal and daylight cameras can help with getting the best performance
from the CM275.
One difference between thermal and daylight cameras has to do with where the energy comes
from to create an image. When viewing an image with an ordinary camera, there has to be some
source of visible light (something hot, such as the sun or other lighting) that reflects off the
objects in the scene to the camera. The same is true with human eyesight; the vast majority of
what people see is based on reflected light energy. On the other hand, the thermal imager
detects energy that is directly radiated from objects in the scene.
This is why hot objects such as parts on engines and exhaust pipes appear white, while the sky,
puddles of water and other cold objects appear dark (or cool). Scenes with familiar objects will
be easy to interpret with some experience.
Infrared energy is part of a complete range of radiation called the electromagnetic spectrum.
The electromagnetic spectrum includes gamma rays, X-rays, ultraviolet, visible, infrared,
microwaves (RADAR), and radio waves. The only difference is their wavelength or frequency. All
of these forms of radiation travel at the speed of light. Infrared radiation lies between the visible
and RADAR portions of the electromagnetic spectrum.
The primary source of infrared radiation is heat or thermal radiation. Any object that has a
temperature radiates in the infrared portion of the electromagnetic spectrum. Even objects that
are very cold, such as an ice cube, emit infrared. When an object is not quite hot enough to
radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may
not give off light, but it does emit infrared radiation, which we feel as heat. The warmer the
object, the more infrared radiation it emits.
Infrared imaging devices produce an image of invisible infrared or “heat” radiation that is
unseen by the human eye. There are no colors or “shades” of gray in infrared, only varying
intensities of radiated energy. The infrared imager converts this energy into an image that we
can interpret.
The FLIR Infrared Training center offers training (including online training) and certification in all
aspects of thermography: http://www.infraredtraining.com/.

remove the test leads from the meter terminals, and set the function switch to the OFF
position before attempting to replace the batteries.
1. Unscrew and remove the battery compartment cover.
2. Replace the three (3) standard AA batteries, observing correct polarity.
