Page 5: Safety Recommendations
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 should 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 lower than actual temperature measurements. • Do not use in a manner not specified in this instruction for use. • Do not use in explosive atmospheres. • Always use the lanyard provided to help minimise damage to the thermal imager and personal injury accidents. • Only use genuine SKF spares and accessories. Other spares and accessories may damage the thermal camera. • The thermal camera contains no user serviceable parts. Opening the imager casing voids warranty. All service work must be carried out by an authorised SKF workshop. SKF TKTI 10... -
Page 6: Description
1. Description The SKF TKTI 10 is a digital camera with advanced thermal imaging capabilities. It is 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 TKTI 10 has a large backlit 3 1/2” colour screen, which gives a clear, sharp resolution using any of the eight 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). Powerful PC software supplied with the TKTI 10, allows the images to be further analysed and to be optimised for ease of interpretation. 2. Getting started 2.1 Contents 1 3 Figure 1.

Page 9: Switching On The Tkti 10
3.2 Switching on the TKTI 10 • The TKTI 10 is switched on and off by pressing and holding down the power button. • The TKTI 10 takes approximately ten seconds to become operational. Figure 6. Camera on/off button 3.3 Focusing Sharpen the image by rotating the focus ring Figure 7. Focusing If the camera is not focused, the thermal image quality will be poor and temperature measurements will not be accurate. To focus make certain that the display blending is less than 100% visible (see chapter 4.2). Rotating the focus ring in a clockwise direction (from user point of view) focuses the images at shorter distances down to a minimum of 30 cm. Rotating the lens in the opposite direction focuses the imager at longer distances up to infinity. Rotate the lens until the image has a sharp definition, with the sharpest contrast at object edges. Focused Not focused Figure 8. Focusing... -

As the visible and thermal camera are not co-incident the visible and thermal image often need to be aligned. This is usually required when inspecting objects at different distances. It is possible to align the thermal and visible (digital) images only on “Live” mode. Further adjustments can be done on the saved images with the software. 1. Press Direct access button 2 to locate the camera on/off option and toggle the centre button to turn the camera option on. 2. Press Direct acces button 1 to locate the alignment option. 3. Alignment presets are accessible with centre toggle button. You can also use the navigation buttons for final adjustment.

Page 16: Menu Infrared Settings
4.4.1 Menu Infrared Settings Infrared • Emissivity Settings Different surfaces can radiate different amounts of infrared energy at the same temperature. This difference in temperature measurement can be corrected for by setting the emissivity value. 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 radiation falling on it; and it is a perfect emitter of radiation. The emissivity of a surface (usually written ε) is the ratio of energy radiated by that surface to 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 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 that temperature measurements be attempted when emissivity values lower than 0.70 are required, because large errors are likely due to reflected radiation from surrounding objects. Set emissivity value between 0.10 and 1.00 for measuring temperature. Pressing Direct access button 3 (ε Table) gives a table of emissivity values of common materials from which a selection can be made. SKF TKTI 10... - Page 17 This is only applicable if an emissivity of less than 1 is selected. Some of the infrared energy seen by the camera from a surface with an emissivity of less than 1.00 is reflected background energy. 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. Infrared • Temperature units Settings Choose between ˚C and ˚F. Infrared • Integration. (1 low to 9 high.) Settings The camera normally operates at a frame rate of 8Hz (i.e. the image is updated 8 times per second). For viewing scenes in which there is very little temperature variation, however, the image may be improved by integrating over several frames to reduce the noise. Chose an integration period from 1 (fast) to 9 (slow). This determines the trade off between display speed and noise. SKF TKTI 10...

Infrared • Interpolation. (On/Off.) Settings Interpolation is on by default as it smoothes the image to provide a better visual image. Turning it off gives a more pixelated image. Some users may wish to observe the scene with the actual resolution of the detector. Actual resolution is 47x47. By turning interpolation on the resolution is interpolated to 180 x180. 4.4.2 Menu Measurement Options This menu enables the selection of options for temperature measurements. The symbols shown below indicate the icons shown for Direct access button 1 when the various options are selected. Measurement • Cursors Options One or two measurement cursors can be selected. When two cursors are chosen, the temperatures at both cursors and the temperature difference between them will be displayed. When one of the cursors is selected by Direct access button 1, it can be moved around on the display by the navigation buttons. cursor centre temperature cursor temperature difference two cursors SKF TKTI 10... - Page 19 Measurement • Tracking Options Select “High”, “Low”, or “High & Low” in order to track and measure the following: • the hottest part of the scene • the coldest part of the scene • or both the hottest and coldest part of the scene. cursor centre temperature cursor temperature difference Tracking Measurement • Area Options Area analysis is useful when wanting to know the highest and lowest temperature in a part of the scene. It also works out the average temperature. There are three area boxes sizes to choose from. - Maximal temperature in the selected area - Minimal temperature in the selected area - Average temperature (surface average).
