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
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.

11.2 Non-Uniformity Correction
A non-uniformity correction (or NUC) is an image correction carried out by the camera software to compensate for different sensitivities of detector elements and other optical and geometrical disturbances1.
The NUC is an automatic function that takes place periodically (approximately every 2-3 minutes) or whenever the inner core of the cameral detects a ±2oC temperature change.

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.
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/.

12. Maintenance
12.1 Cleaning and Storage
Wipe the housing with a damp cloth as needed. Use a high-quality lens wipe to remove dirt or smudges from the meter lenses and display window. Please do not use abrasives or solvents to clean the meter housing, lenses, or display window.
If the meter is not to be used for an extended period, remove the batteries and store them separately.
12.2 Battery Replacement
The Battery symbol flashes critical level. The meter displays readings within specifications while the low battery indicator is on. The meter powers off before it displays an out of tolerance reading.
WARNING: To avoid electrical shock, disconnect the meter from any connected circuits, 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.
3. If using the Model TA04 rechargeable lithium polymer battery system, please
recharge the rechargeable battery.
4. Secure the battery compartment cover.
12.3 Disposal of Electronic Waste
As with most electronic products, this equipment must be disposed of in an environmentally friendly way, and in accordance with existing regulations for electronic waste. Please contact your FLIR Systems representative for more details.
