PREC AUTIONS FOR US E
An infrared camera is a sensitive optical measuring device. It is not a medical device.
Never aim the camera towards the sun or other source of intense thermal radiation (e.g. welding, cutting, and similar
operations).
If parts of the camera are damaged or present problems following failure to heed the warnings listed above,neither the manufacturer
nor the distributor shall be held liable, and all costs incurred shall be borne solely by the operator.
INTRODUCTION
Infrared thermography detection technology has been in existence for many years in industrialized countries, where it has become
an indispensable means ensuring safety in industrial production. It is used in sectors of industry as diverse as metallurgy and steel-
making, electric power, petroleum, automation, the exploitation of natural gas, and transportation, and in other committed
professionssuch as fire-fighting and bordersurveillance. In all of these activities, characterized by just-in-time operating procedures,
high-voltage production equipment, powerful electric currents, and/or high operating speeds, infrared thermal imaging provides a
real-time non-contact inspection method.
This detection method does not require you to cut off the power, shut down the machines or interrupt production. It can diagnose
latent malfunctionsin advance, and so forestall theiroccurrence and prevent productionincidents. Thermal imaging is an innovative
non-contact evaluation technique that is safe, reliable, and rapid.
Compared to the contact-based detection instruments still widely used, this new technology is revolutionary. Infrared thermal
imaging detection technology has major applications in the following fields:
surveillance of electrical equipment and high-voltage transformers
locating leaks from thermal equipment and heat exchangers; analysis of heat losses
identification of thermal failures in rail transport
in the micro-electronics industry, rationalization of circuits by detection of systematic hot spots
fire-fighting, locating latent fire sources
at a fire, aid to victims and tactical command
security professionals, night time surveillance
This is why infrared thermal imaging detection technology is currently regarded by all concerned as the cutting edge in many
fields.
Thermography can also be used to take a body temperature.
Given that a fever is often a sign of an infectious disease, a specialized camera can be used to detect an abnormal elevation of
temperature and thereby contribute to reducing the risks of contagion.

1. GETTING STARTED
1.1. Elementary precautions
1.1.1. Never aim the camera towards the sun or other source of intense thermal radiation
Direct exposure to sunlight or other strong thermal radiation can impair the operation of the camera and make the infrared sensor
partially or totally inoperative for as long as several months.
We therefore recommend closing the lens flap when the camera is not in use, to avoid any accidental exposure.
1.1.2. Avoid exposing to dust with the lens flap open
Even though it is rated IP54 (dust and splash protected), it is best not to use the camera in a dusty environment: dust deposited on
the lens can not only perturb the measurements (absorption of part of the thermal flux and spurious diffusion) but also impair the
sharpness of the images.
To clean your lens, refer to §9.2 Cleaning the infrared optics.
1.1.3. Do not touch the lens with your fingers.
Finger marks must be carefully avoided, because acids from the skin attack the coatings and the glass of the lens; they can leave
indelible traces. Refer to §9.2 Cleaning the infrared optics.
1.1.4. Avoid jolting or dropping the camera.
The camera is rugged, but even so it is a delicate precision instrument which should not be jolted or dropped.

1.2. Powering the camera
Spent primary and storage batteries must not be
treated as ordinary household waste. Take them to the
appropriate collection point for recycling.
The camera acceptsAA batteries of two types:
- either alkaline batteries
- or Ni-MH rechargeable batteries.
- or an adapter for a USB power supply (optional).

The latter must be recharged with an external charger.

When the batteries are withdrawn, the internal clock
has enough power for 15 hours.

The batteries are inserted through the end of the
handle.

Open the cover using a coin while pressing down on
the locking tab:

Once the power supply is in place, you must configure
the battery manager (see 1.4.1. Battery management)

8
1.3. Inserting the micro SD memory card
The files created by the camera (image, audio, and setup
files) are stored only on the micro SD memory card located
on the left side of the head.
If this card is missing, an error message appears as soon as
access to it becomes necessary.
The memory card must be formatted:
- either in FAT16 format,
- or in FAT32,
or it cannot be read.
To insert the card, open the rubber flap and push the card into
its slot. Refer to the diagram opposite.
Take care to insert it in the right direction.
If the card cannot be inserted:
- either it is in the wrong direction and must be turned
around;
- or there is already a card in the slot.
1.4. Organization of the display
In principle, the camera starts up:
in its main display,
in continuous acquisition mode,
with the setup loaded when it was last switched off.
However, after the batteries have been withdrawn, when the camera is started up, a "Battery Management" menu is displayed
(unless the type of power supply selected is "USB supply").
It can be displayed on demand, by keeping the F2 key pressed when the camera is started up.
Information messages may be superimposed on this screen (example: messages for reconnection of the Bluetooth peripherals if
they had been used, or error/information messages, as the case may be).
The system date and time entry menu is displayed if the power supply to the internal clock has been interrupted. It is recommended
in this case to update this information, which is used in the names of the image files.
1.4.1. Battery management
The camera can have its own power supply (rechargeable or primary batteries) or be powered via a USB power supply kit that is
connected to mains.
To inform the operator of the state of the batteries during operation, the camera has a battery indicator in the status bar of the
main screen (see §1.4.2.1. Status bar).
This indicator is updated by a battery manager that is configured in the "Battery Management" menu.
This menu appears when the device is first switched on after the batteries have been removed (unless "USB Supply" has been
selected previously). To call it up on demand, press the F2 key when the camera is switched on. This is necessary in particular to
return to an internal power supply mode and reactivate management of the battery gauge.
With the internal power supply, the battery manager serves to track energy consumption and thereby provide an estimate of how
much energy is left. For a good estimate of battery life, the right information must be entered in the menu: select the type of
battery inserted (rechargeable or primary) and enter a consistent theoretical capacity. The manager assumes that when inserted,
the batteries are fully charged.

With the USB adapter, the manager is no longer actuated and the batteries will always appear as fully charged in the status bar.
The camera will remain on until switched off by the user or by the auto-off system. It may be useful in this mode to deactivate the
instrument's auto-off function so that the camera remains on at all times (see 1.5.5. Setting the time before automatic shutdown of
the camera).
Warning: Like all the other parameters entered by the user, these values are stored in lasting form when the camera is
switched off by the i/o key of the keypad (the information is lost if there is a power outage).
F1 confirms the information entered, closes the window
and initializes the battery manager with these settings.
F2 edits and confirms entry of the selected item.
F3 cancels an entry or closes the window without
resetting the battery manager.
Type of batteries: The camera is delivered with low-self-discharge Ni-MH rechargeable batteries with a capacity of approx.
2500 mAh. These are the default parameters.
If the user always uses the same set of rechargeable batteries, it may be useful to operate until the camera
automatically switches off because the batteries are low. In this case, the theoretical capacity of the
batteries entered at the outset is automatically adjusted in light of the actual discharge. This new capacity
is proposed by default the next time the menu is displayed.
