Introduction The Fluke Ti20 Imager (hereafter, “the Imager”) is a state-of-the-art, lightweight, pistol- grip style thermal imaging unit. Using the Imager, you can obtain instant and accurate thermal images and radiometric readings from distant targets. The Imager is ergonomically designed for right-hand or left-hand use, and captures thermal images and data with a simple trigger press.
Ti20 Users Manual Safety Information Use the Imager only as specified in this manual. See Table 1 for a list of symbols used on the Imager and in this manual. A W Warning identifies hazardous conditions and actions that could cause bodily harm or death.

Ti20 Users Manual Number Zone Information Aiming and Activating the Laser The laser is a sighting aid and is not required to take measurements. The laser is not coaxial with the infrared channel, and the laser dot is offset from the center of the thermal image (the crosshatch at the center of the display).
The Japanese model of the Ti20 requires you to press and hold F to turn on the laser and keep it on. When you release F, the laser turns off. Capturing Images Recording images is a simple process but before starting you should note the current image location number.
Ti20 Users Manual If no image is stored at the current memory location, the right side of the display is black. 3. Press G ( image location. Adjusting the Backlight Backlight ON is recommended for indoor use set the backlight OFF for outdoor applications and to save battery life.
Setting the Temperature Scale The Imager displays temperatures using either the Celsius or Fahrenheit temperature scales. The default temperature scale is Celsius. 1. Press G ( MENU scale function. 2. Press H (TEMPSCALE Celsius. Setting the Level In Manual mode, you can define Level and Span values manually. Manual mode allows you to bring both MIN and MAX values to the desired cut-off levels and to adjust the temperature interval to a minimum to maximizing color resolution.

Using Distance to Spot Size Ratio (D:S) The Ti20 imager views a portion of the scene that is 15 º high by 20 º wide (the Field-Of- View (FOV), of the Imager) as shown in Figure 2-3. This scene is displayed on the LCD on the back of the Imager.

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 Imager optics. Noise, electromagnetic fields, or vibration are other conditions that can interfere with temperature measurements, and should be considered before starting temperature measurements.
Ti20 Users Manual Emissivity Emissivity is the measure of an object's ability to emit infrared energy. The hotter an object, the more infrared energy it will emit. Emissivity can have a value from 0 (shiny mirror, perfect reflector) to 1.0 (blackbody, perfect emitter). Most organic, painted, or oxidized surfaces have emissivity values close to 0.95.
Reflected Temperature Compensation Targets that have low emissivities will reflect energy from nearby objects. This additional reflected energy is added to target’s own emitted energy and may result in inaccurate readings. In some situations objects near the target (machines, furnaces, or other heat sources) have a temperature much higher than that of the target.

Appendix A Glossary Absolute Zero The temperature (0 degrees Kelvin) of an object defined by the theoretical condition where the object has zero energy. Accuracy Maximum deviation, expressed in temperature units, or as a percentage of the temperature reading, or as a percentage of the full scale temperature value, or as a percentage of the target temperature, indicating the difference between a temperature reading given by an instrument under ideal operating conditions, and the temperature of a calibration source (per the ASTM standard test method E 1256-88).

Ti20 Users Manual Level Level is the median point of a given temperature scale. For example, if the unit is currently in Automatic mode, and there is a given thermal scene with MIN and MAX temperature limits, the moment you switch the unit to Manual mode, the Level value is set by the unit according to the following formula: Micron (or µm)

The specification for Fluke instruments also includes the average time required for software computations. Scatter (Size of Source Effect) An undesirable increase in temperature reading caused by IR energy outside the spot reaching the detector.

Ti20 Users Manual Stare A saturation effect caused by aiming a sensor at a hot target for an extended period of time and then quickly aiming at a target at a lower temperature. The increase in time (beyond the normal system response) for the sensor to return to within 5 % of the lower temperature is defined as the stare time.
Appendix B Basics of Infrared Measurement Q. Why use non-contact infrared thermometers? Non-contact 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. The temperature is shown on the LCD display.
Page 58
Ti20 Users Manual Gamma X-Rays Ultraviolet Rays 0.1 A 1 UA 100 A Q. How to assure accurate temperature measurement? A. A solid understanding of infrared technology and its principles lies behind accurate temperature measurement. When the temperature is measured by a non-contact device the IR energy emitted from the measured object passes through the optical system of the thermometer or thermal imager and is converted to an electrical signal at the detector.
