Page 4: Safety Recommendations
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. SKF TKTI 21 & 31... -
Page 5: Introduction
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 SKF TKTI 21 & 31... -

Page 9: Charging The Battery
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 SKF TKTI 21 & 31... -

Page 18: Level/Span
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. SKF TKTI 21 & 31... -

Page 22: Emissivity
The amount of infrared radiation emitted by a surface depends on both its temperature and its emissivity. Surfaces that are good reflectors (e.g. polished metal) are poor emitters, and surfaces that are good emitters (e.g. human skin) are poor reflectors. A black body is defined as an object that absorbs all the radiations falling on it and it is also a perfect emitter of radiation. The emissivity of a surface (usually written ε) is the ratio of the energy radiated by that surface to the energy radiated by a black body at the same temperature. For accurate temperature measurements, the emissivity of the surface being measured must be entered into the camera. This is done by entering a number in the range from 0.10 (for polished chromium) to 1.00 (for a black body). An emissivity lookup table is provided, which lists the emissivities of a range of common materials. It is not recommended to use the camera on surfaces with an emissivity below 0.7. The global emissivity can be set via the Adjustment menu. Select Setup->Adjustment to open the Adjustment dialog box. Figure 23 Emissivity adjustment The user can set the global emissivity, temperature correct and ambient temperature. • Emissivity: The emissivity can be entered manually or chosen from a list of materials by clicking on Customize. See a list of common emissivities in chapter 6.2. • TCorrect: Temperature correction setup. • TReflect: Some of the infrared energy seen by the camera is reflected by the background. If there is a hot object in the background, this can have a significant effect on the temperature measured. By entering a reflected temperature value, the camera can correct for the effect of this reflected background energy. Usually set to the ambient temperature. The emissivity of each cursor, area or line can also be individually adjusted after these elements have been created (see 3.4.2 A button) SKF TKTI 21 & 31... -
