Laser Sighting 3 3.1 Warnings and Cautions CAUTION You may receive harmful laser radiation exposure if you do not adhere to the warnings listed below: • USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HERE MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. • DO NOT LOOK AT THE LASER BEAM COMING OUT OF THE LENS OR VIEW DIRECTLY WITH OPTICAL INSTRUMENTS EYE DAMAGE CAN RESULT. • USE EXTREME CAUTION WHEN OPERATING THE LASER SIGHTING. • NEVER POINT THE LASER BEAM AT A PERSON.
3 Laser Sighting 3.2 Description The Laser Sighting is built into the thermometer. It provides a visual indication of the field of view of the thermometer. Aiming at distant targets (up to 40 feet) becomes much easier by using the Laser Sighting. It is offered in two different models, laser dot, and laser dot/circle switchable. The Laser can be set to either flashing or continous.
Laser Sighting 3 3.3 Operating the Laser Sighting 1. Set the laser power switch to the ON position as shown in Figure 3-2. 2. Aim at the target and pull the trigger. 3. The laser beam and the red power indicator LED will turn on. Refer to Figure 3-1 and Figure 3-2. The laser beam will stay on as long as the trigger is pulled. If the trigger is locked (the LOCK key is previously pressed) or released, the laser beam will turn off. In order to turn on the Laser Sighting, pull the trigger again. 4.
3 Laser Sighting NOTE The Laser Sighting turns on only when used with the thermometer. The module does not turn on by itself. The line of sight of the thermometer does not coincide with that of the Laser Sighting, as shown in Figure 3-4. The two lines of sight become less critical when measuring distant targets. For example, at 30 feet from the target and a 3 foot diameter target size, there is a 2.7% offset error with respect to the target size.
Sighting Scope 4 4.1 Sighting Scope The Sighting scope is an accessory for the thermometer. It provides a visual indication of the target being measured. Aiming at distant targets (up to 200 feet) becomes much easier by using the Sighting scope. 4.2 Installing and Operating the Sighting Scope 1. If the sighting scope is already installed on the thermometer, go onto step 5. 2. The sighting scope comes with a pair of mounting clamps already attached. 3.

Maintenance 6 6.1 Replacing the Batteries NOTE When you change the batteries, all of the set parameters (i.e. emissivity, high alarm, low alarm, Target Ambient Temperature) will be reset to the default values. For your convenience, you may want to write down all of the set parameters BEFORE replacing the batteries. The thermometer is powered by 4 standard AA size lithium batteries. To replace the batteries: 1. Invert the thermometer and open the cover of the battery compartment. 2.
6 Maintenance 6.2 Cleaning the Lens Although all lenses are quite durable, take care to prevent scratching when cleaning them. To clean the lens: 1. Blow off loose particles, using clean air. 2. Gently brush off remaining particles, using a camel hair brush. Alternatively, clean any remaining contaminants with a damp, soft, clean cloth. Be careful not to rub too hard. CAUTION Do not use any ammonia or cleaners with ammonia on the lens, as damage may result.

Appendix: How Infrared Thermometry Works A Thermal Radiation Heat is transferred from all objects via radiation in the form of electromagnetic waves or by conduction or convection. All objects having a temperature greater than absolute zero (-273°C, -459°F, 0 K) radiate energy. The thermal energy radiated by an object increases as the object gets hotter. Measurement of this thermal energy allows an infrared thermometer to calculate the object’s temperature if the emissivity (blackness) is known.
A Appendix: How Infrared Thermometry Works Blackbody When thermal radiation falls on an object, part of the energy is transmitted through the object, part is reflected and part is absorbed. A blackbody is defined as an ideal object that absorbs all the radiation incident upon it. The best example of a real object that acts like a blackbody is a small hole drilled deep into a large opaque cavity.
Appendix: How Infrared Thermometry Works A Wien’s Displacement Law describes the exact mathematical relationship between the temperature of a blackbody and the wavelength of the maximum intensity radiation. λm = 2.898 T where λm = wavelength measured in microns T = temperature in Kelvin Calculating Temperature The net thermal power radiated by an object has been shown to depend on its emissivity, its temperature and that of the ambient temperature around the object.
A Appendix: How Infrared Thermometry Works Optics Field of View Accurate measurement of temperature via infrared means depends strongly on the size of the object and the distance between the thermometer and the object. All optical devices (e.g. cameras, microscopes, infrared thermometers) have an angle of vision, known as a field of view or FOV, within which they see all objects. In particular, the thermometer will measure a fixed proportion of the energy radiated by all objects within its FOV.
Appendix: Emissivity Values B Table B-1 provides guidelines for estimating the emissivity of various common materials. Actual emissivity, especially of metals, can vary greatly depending upon surface finish, oxidation, or the presence of contaminants. Also, emissivity or infrared radiation for some materials varies with wavelength and temperature. To determine the exact emissivities for most applications, follow the procedures in Appendix C. Table B-1.

Appendix: Determining an Unknown Emissivity C In Appendix A, we showed how emissivity is an important parameter in calculating the temperature of an object via infrared means. In this section we discuss how to determine a specific emissivity value. If you know the material of the object, use Table B1 in Appendix B to look up its approximate emissivity. Most organic materials such as plastics, cloth, or wood have an emissivity of about 0.95. For this reason, we use 0.
C Appendix: Determining an Unknown Emissivity Method 3 1. Use this method to measure objects at temperatures below 260°C (500°F). 2. Place a large piece of masking tape on the object (or at least a sample of the object material). Allow time for the masking tape to reach the object temperature. 3. Set the emissivity of the thermometer to 0.95. Use the thermometer to measure and record the temperature of the masking tape - Area ‘A’ in Figure C-1.
Appendix - Determining an Unknown Emissivity C Method 4 1. Paint a sample of the object material with flat black lacquer paint. 2. Set the emissivity to 0.97 and measure and record the temperature of the painted portion of the sample material - Area ‘A’ in Figure C-1. Make sure that the painted area of object material fills the FOV of the thermometer. 3. Aim the thermometer at another spot on the target - Area ‘B’ in Figure C-1. 4.
