Chapter 4 Obtaining the Best Image The Importance of Focusing The focusing ability of the imager is similar to the one found on regular photographic cameras, and it is defined as the ability to adjust.
Tip: When focusing an image, look for identifiable patterns or shapes on the object surface that can help establishing the best image definition. Objects contours, dividing lines or limits are particularly useful. Proper focusing is not only important to the image quality, but also greatly affects the accuracy of temperature measurements.
temperature value in the scene (MAX). The MIN and MAX values are displayed at the beginning and at the end of color scale. This mode does not require any other adjustment (other than properly focusing the unit). Automatic mode is recommended every time the user first starts looking at a given target since the temperature limits are unknown.
Graphically, it would look like this: The imager automatically calculates Level and Gain when switched from Automatic to Manual or Semi Automatic modes, thus providing a smooth and meaningful transition of the thermal boundaries of the scene.
In Manual mode the user can adjust Gain and Level manually. Use this measurement mode when you need more freedom to define Level and Gain values. This mode provides the flexibility to bring both MIN and MAX values to the desired cut-off levels and to adjust the temperature interval to a minimum, thus maximizing color resolution.
Chapter 5 Qualitative and Quantitative Temperature Measurements Most of the time thermal imager users are measuring apparent temperatures that are inextricably linked to qualitative inspections. Qualitative inspections focus on temperature differences as opposed to actual temperatures .
D:S ratio: D / S = 90 The number “90” means that at a distance D equal to 1 meter the unit will measure a circle of diameter S equal to 1.1cm (1meter divided by 90); at distance D equal to 2 meters it will measure a circle with diameter S equal to 2.
Figure 30. Field of View Tip: When accuracy is critical make sure that the target is at least twice as large as the spot size. Environmental Conditions Watch for environmental conditions in the working area. Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the path between the target and the unit's optics.
Emissivity Emissivity is the measure of an object's ability to emit infrared energy. Emitted infrared energy is exponentially proportional to the temperature of the object. Emissivity can have a value from 0 (shiny mirror, perfect reflector) to 1.
furnaces, or other heat sources) have a temperature much higher than that of the target. In these situations it is necessary to compensate for the reflected energy from those objects. Note: The Reflected Temperature Compensation (RTC) feature is disabled if the emissivity is set to 1.
Chapter 6 Organizing Your Data The ThermoView imager when used together with the InsideIR software provides a powerful way to organize and track maintenance data.
Uploading Data to the Imager Click the Upload Setup Imager button on the InsideIR main screen to upload data to the ThermoView imager. This displays the following screen: Select the folder and session you want to upload and press Next . Figure 33. Uploading Data to Your ThermoView Ti30 Imager July 1, 2003 - 52 - Version 1.
If you wish to change parameters for different locations such as location name, emissivity, reflected temperature compensation, low and high alarms, and comments, you can do so by right-clicking the thumbnail of the image you wish to edit, clicking Edit data in the pop-up menu, and changing the desired field(s).
Note 2: If you wish to restore the default parameters on the unit press the Restore button. By doing this all 100 locations on the imager will be restored with the factory parameters.
Chapter 7 Analyzing Your Data There are many ways to analyze your thermal data now that you have it downloaded and organized. After clicking on a thumbnail in the Main InsideIR screen, the data for that specific thermal image is displayed in one of four tabs: Image, Temperature Table, Profile, and Histogram.

Appendix B – Infrared Theory Q&A Q. Why use noncontact infrared thermometers? A. Noncontact infrared (IR) thermometers use infrared technology to quickly and conveniently measure the surface temperature of objects. They provide fast temperature readings without physically touching the object.
Q. How to assure accurate temperature measurement? A. A solid understanding of infrared technology and its principles lies behind accurate temperature measurement.
temperature of a shiny object you can compensate by covering the surface to be measured with masking tape or flat black paint. Allow time for the tape or paint to reach the same temperature as the material underneath. Measure the temperature of the taped or painted surface.
that the target is at least twice as large as the spot size. Q. How to take temperature measurement? A. To take a temperature measurement, just point the unit at the object you wish to measure. Be sure to consider distance-to-spot size ratio and field of view.
Glossary Absolute Zero The temperature (0 Kelvin) of an object defined by the theoretical condition where the object has zero energy. Accuracy Maximum deviation, expressed in temperature units, or as .
Background Temperature Temperature behind and surrounding the target, as viewed from the instrument. Blackbody A perfect emitter; an object that absorbs all the radiant energy incident on it at all wavelengths and reflects and transmits none. A surface with emissivity of unity (1.
Display Resolution The level of precision to which a temperature value can be displayed, usually expressed in degrees or tenths of degrees. Drift The change in instrument indication over a long period of time, not caused by external influences on the device (per the ASTM standard test method E 1256-88).
Focus Point (or Distance) The distance from the instrument where the optical resolution is greatest. Full Scale The maximum of the temperature range or output signal. Full Scale Accuracy A convention for expressing the accuracy as percentage of an instrument’s (highest) full- scale temperature.
