THERMAL CAMERA

ATTENTION
An infrared camera is a sensitive optical measuring device. Pay special attention to the following points:
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
professions such as fire-fighting and border surveillance. 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 malfunctions in advance, and so forestall their occurrence and prevent production incidents. 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 industrial
surveillance.
Thank you for purchasing a C.A 1954 thermal camera.

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.
1.1.5. Do not point the laser pointer at a person's eyes
The camera has a laser pointer.*
Warning! Do not aim the laser beam towards a person's eyes, which could cause burns.

1.2. Powering the camera
The camera acceptsAA batteries of two types:
- either alkaline batteries
- or Ni-MH rechargeable batteries.

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:
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.
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
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). The battery manager can be controlled in two ways:
1. default mode
the operator is not required to enter any information, but is informed when the charge level of the batteries is low:
- no display before this low level is detected,
- display of approximately 30 minutes before automatic shutdown of the instrument.
2. advanced mode
This allows precise tracking of consumption, provided that the necessary data are correctly entered, namely:
- the type of batteries used,
- their theoretical capacity.
This battery manager assumes that the batteries inserted before the data are entered are fully charged.
The "Battery Management" menu selects the operating mode:
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.
The "Advanced" item determines whether the advanced mode is
active or not:
- Pressing F2 edits the value of the item.
- The Up/Down arrows select a value and F2
confirms entry.
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.

1.4.2. Main screen
The screen is divided into 4 zones:
Status bar
Cursor main
measurement
Secondary measurements at
cursors
Bluetooth measurements
Palette of colours
Cursor surface

Functions of the
F1, F2, and F3 keys
An image covers the entire surface of the screen; the following items are superimposed on it:

status bar

palette of colours

the display of the main and secondary measurements (in IR)

the display of the Bluetooth measurements (on request)

the functions of function keys F1, F2, and F3

1.4.2.2. Palette of colours
The colour palette is used to identify the temperatures of the various colours used on the thermogram. By default, this
temperature/colour assignment is done automatically as a function of the minimum and maximum temperatures read in each
image. But the operator can also fix this relation by forcing the min. and max. temperatures: imposing a "frozen" palette
(see § 2.7. Freezing the colours representing the temperatures ).
In the automatic mode, the palette is represented as follows:
When the palette is frozen, the min. and max. temperatures
are shown in red and a padlock appears in the centre:
