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

3.1 Battery
3.1.1 Battery Installation and Replacement
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.

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.

3.3 Focusing
• Sharpen the
image by rotating
the focus ring
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.
