Safety recommendations
Warning
• The equipment described in this document uses a Class 2 laser.
Do not look directly into the laser beam or the laser beam exit aperture,
irreversible damage to the eye may occur. The laser must not be operated
when there are personnel in the camera’s field of view.
Caution
• Use of controls or adjustments or performance of procedures other than
those specified in this document may result in hazardous laser radiation
exposure.
• To help minimize burn hazards, be aware that thermal images of
highly reflective objects will show a lower temperature than their actual
temperature.
• Do not use in a manner not specified in this instruction for use.
• Do not use in explosive atmospheres.
• The thermal camera contains no user serviceable parts.
Opening the casing voids the warranty. All service work must be carried
out by an authorized SKF workshop.
• Never point the lens directly towards a strong radiation source
(eg. Sun, direct or reflected laser beam, etc ), with power on or power off,
as permanent damage may result to the thermal detector of the camera.
• Store the unit in its original case in a cool, dry, well-ventilated area away
from strong electromagnetic fields.
• Protect the surface of the lens from being stained or damaged by foreign
objects such as sludge or chemicals. Place the lens cap back on the lens
after use.
• For best measurement accuracy, allow 3 to 5 minutes for the camera to
stabilize after initial start up.

1. Introduction
The SKF TKTI 21 and SKF TKTI 31 are rugged handheld digital cameras with advanced
thermal imaging capabilities.
They are ideal for use as a Predictive Maintenance (PdM) tool. Thermography is a non-
invasive technique and is well suited for mechanical and electrical inspections, energy
conservation and plant safety activities.
The cameras have a large 3.5” colour screen, which gives a clear, sharp image using any
of the eleven colour palettes. Designed for easy operation, multiple temperatures can be
measured and the differences between them displayed. Other advanced measurement
options are also available. Images can be stored as radiometric data and digital images on
the micro SD card (supplied). The powerful PC software allows the images to be further
analyzed and exhaustive reports to be created.
Instructions for use for the PC software can be found on the CD or on SKF.com

The Battery door is located in the bottom of the handle. Open the lock on the battery door
by pushing in the direction shown figure 4.
Figure 4 Battery door Figure 5 Battery insertion
Insert one of the two batteries supplied as shown on Figure 5. Ensure the battery
contacts are oriented towards the upper part of the camera. Lock the door.

SKF TKTI 21 & 31
3.1.2 Charging the Battery
For charging the battery, remove the battery from the camera. Place the battery in the
battery charger provided. To fully charge the battery will take around 3 hours.
Two batteries are supplied in order to allow continuous operation of the camera.
When placing the battery on the battery charger, check the contact to make sure the
charger light becomes red.
Note:
Before first use, it is recommended to fully charge the batteries.
Alternatively the battery can be charged by connecting a 12V DC 3A max power adapter
to the 12V connector located on the side of the camera.
3.1.3 Battery safety and usage
Batteries should be stored at ambient temperature of -20 °C (-4 °F) to +20 °C (68 °F).
Lithium batteries will self-discharge during storage, so they should be fully charged before
storage. Self-discharge may affect long term battery performance.
Furthermore, it is recommended that the battery should be fully charged every 3 months.
CAUTION:
The use of an incorrect battery may result in physical or electrical damage to the
instrument due to incorrect voltage or physical size difference. The ambient temperature
for charging should be between 0 °C (32 °F) and +40 °C (104 °F).
When using the camera under 0 °C (32 °F)ambient temperature, the battery capacity
will be reduced, over +50 °C (122 °F), the battery may overheat, resulting in permanent
damage.
WARNING:
• Never disassemble, incinerate or puncture battery
• Never short circuit the battery
• Keep the battery dry
• Keep out of reach of children
• Always dispose of the battery in accordance with local regulations

3.2 Switching On the Camera
The Thermal camera is switched On and Off by pressing and holding the On/Off button for
at least 3 seconds, until the display switches On.
The clicking noise heard frequently when the camera is switched On is due to the
calibration of the Infrared detector. This is done automatically by the camera.
Note:
After powering off, please wait ten seconds before switching On the camera again.

Figure 7 Focusing
REMEMBER TO REMOVE THE LENS CAP
Focus:
• Is the most important step to obtain a good quality image.
• Influences the accuracy of the temperature reading.
• Cannot be modified when viewing the images on a PC.
• Some palettes allow you to make a better focus.
• Make sure you are in automatic span and level.

11
SKF TKTI 21 & 31
• Rotating the focus ring in a clockwise direction (from user point of view) focuses at
shorter distances down to a minimum of 10 cm.
• Rotating the lens in the anti-clockwise direction focuses at longer distances up to
infinity.
• Rotate the lens until the image has a sharp definition, with the sharpest contrast at
object edges.

The Measurement dialog box will be displayed.
• Toggle through the options and press the Okay button to select the required item or
the C button to cancel.
The available options are:
• None – Deletes all measurements from the screen.
• Add Hot Spot – adds a moving cursor that automatically displays the hottest spot in
the image. Designated by SH and +H.
• Add Cold Spot – adds a moving cursor that automatically displays the coldest spot in
the image. Designated by SL and +L.
• Add Spot – adds up to 2 fixed cursors, user adjustable by the cursor editing mode.
Designated by S1, +1 and S2, +2.
A temperature profile is a histogram showing the temperature values through a
cross-section of the scene.
The horizontal or vertical cross-section can be moved by the user.
• Horizontal – Adds horizontal line measurement to display profile of temperatures
along the line. Designated by LH.
• Vertical – Adds vertical line measurement to display profile of temperature along the
vertical line. Designated by LV.
Note:
Either Horizontal or Vertical can be enabled at a time.
• Area – adds up to 3 area boxes, with min, max or average temperature displayed for
each box. Areas can be sized and moved by the user.
Note:
To delete a single object, press A button to select the object and then press C button to
delete.
The emissivity will be set to the global emissivity when the cursors are added.
The emissivity of each cursor can be individually adjusted.

4.2.2 Level/Span
The span is defined by the minimum and maximum temperatures on the scale on the
bottom side of the screen. A wider span will give you less thermal details, whereas a
narrower span will give you more thermal details but also increases the noise in the
image.
You can adjust its position within the range, this is the level setting.
By adjusting the temperature and colour corresponding relation, users can observe
enhanced image quality and easily find and analyze thermal fault.
There are two operational modes available Automatic or Manual.
• In Auto mode, the camera automatically adjusts the image to allow for the highest
and lowest temperature in the scene. This is useful when starting the camera and
switching to different parts of a scene.
• In Manual mode, the user defines the range of temperatures to be displayed. Manual
setting is useful when the user wants to examine specific parts of the image. In a
fixed temperature range, anomalies or discrepancies can be precisely highlighted.
Press the Menu button to enter the menu
• To switch between Manual and Auto, select Level/Span from the menu and
validate L/S? for manual or Auto? for automatic.
Figure 17 Auto or Manual mode
In Manual mode press the left or right arrow will reduce or increase the Span and
pressing the up or down arrow will reduce or increase the Level.
In Manual mode, L/S symbol is shown in the top left of the screen to indicate the Level
and Span can me manually adjusted.
