1 Model No. English Instruction SheetPage 1 Model 65 Infrared ThermometerInstruction SheetIntroductionThe fluke Model 65 Infrared Thermometer ( the Thermometer ) isa noncontact Thermometer with laser pointer. The thermometerdetermines an object's surface temperature by measuring theamount of Infrared energy radiated by the thermometers can be used to measure surfacetemperatures that are unsuitable for traditional contactmeasurement methods (such as moving objects, electrically livesurfaces, and difficult-to-reach objects).Box ContentsThermometer, holster, carrying case, 2 AA alkaline batteries (notinstalled), Quick Reference Card, Registration Card, Warrantyinformation, and a CD-ROM containing the full set of FlukeTo contact fluke call:1-888-99- fluke (1-888-993-5853) in USA1-800-36- fluke (1-800-363-5853) in Canada+31-402-678-200 in Europe+81-3-3434-0181 Japan+65-738-5655 Singapore+1-425-356-5500 in other countriesVisit fluke s web site at: 1999, , 9/02 1998,2002 fluke Corporation, All rights No.

2 English Instruction SheetPage 2 WWarningTo avoid possible personal injury: Caution - performance of procedures other thanthose specified herein may result in hazardouslight exposure. Do not stare into the laser beam or direct ittoward the avoid possible damage to the Thermometer orincorrect measurements: Do not drop the Thermometer or subject it toviolent shocks. Do not operate the Thermometer near largeelectrical or magnetic fields. Do not touch the object with the Thermometer . If the emissivity of the object is not , thethermometer can indicate a temperaturedifferent from the actual temperature. (See"Emissivity.") Keep the Thermometer away from directsunlight or a strong source of light, hot objects(70 oC / 158 oF), high temperatures, highhumidity, or dust during use and storage.

3 Do not apply sudden temperature changes tothe Thermometer . Before taking measurements,wait for the Thermometer to return to a stabletemperature. Do not touch the focal lens. Condensation may form on the focal lens if thethermometer moves quickly from a cold to a hotenvironment. Before taking measurements, waitfor the condensation to No. English Instruction SheetPage 3 ComponentsMINMAXMEMORYRECALL F CPress 1 SecondSAVE TEMP Focal lens Laser aperture Pushbuttons Holster Display Laser safety label Battery door release Batteries Backlight switch Laser switchModel No. English Instruction SheetPage 4 PushbuttonsPushbuttonDescriptionGPress and hold G to display the object's surfacetemperature.

The laserpointer only activates if the laser switch is in the G is pressed, the display shows G to stop measuring temperatures anddeactivate the laser. The display continues to showthe most recent temperature and Cfor 20seconds. Then the display turns F to display the maximum measuredtemperature. The display shows F a second time to display the minimummeasured temperature. The display shows F a third time to turn off this E and hold for 1 second to save thedisplayed temperature. The display flashes TEMPMEM 5 times to indicate that the operation E to display a stored temperature.

Emissivity is determined primarilyby the object's composition and surface finish.

6 A polished, non-oxidized metallic surface has an emissivity value near 0 and adull, black surface has an emissivity value near 1. (See"Emissivity of Common Materials.")The Thermometer 's sensitivity to emissivity is set at the factory If the emissivity of the object is not , the displayedtemperature could differ from the actual surface temperature. Toreduce this difference, apply black tape, black matte paint, orblack magic marker to the object if it is safe to do so andmeasure the darkened No. English Instruction SheetPage 6 Optical ResolutionOptical resolution (also called "Field of View" or "Distance-to-Spot-Size Ratio") is the ratio of the Thermometer 's distance fromthe object's surface to the size of the area measured ("spotsize").

7 The closer the Thermometer is to the object, the smallerthe spot size. The laser spot size does not indicate the measuredspot size. (See "Laser Offset.")The Thermometer has an 8:1 optical mm(8 in)400 mm(16 in)600 mm(24 in)800 mm(32 in)Spot Size25 mm(1 in)50 mm(2 in)75 mm(3 in)100 mm(4 in)The minimum spot size is 25 mm (1 in), which occurs at adistance of 200 mm (8 in) from the object. You cannot measure asmaller spot size by getting temperature displayed is an average temperature within thespot size. Hot spots can be missed if the spot size is too as close as possible but no closer than 200 mm (8 in).Laser OffsetThe laser beam is offset 18 mm ( in) from the focal a sampling spot large enough to include the laser TemperaturesThe Thermometer measures the first surface it detects, even aglass cover, dust, or fog.

8 Make sure the object is not No. English Instruction SheetPage 7 Measuring TemperaturesRead the section "Ensuring Accuracy " before measuringtemperatures. Check that the batteries are installed and the laserswitch is in the on position. (See the sections "Installing theBatteries" and "Setting the Switches.")To take a measurement:1. If the emissivity of the object is different from , applyblack tape, black matte paint, or black magic marker to theobject if it is safe to do so. (See the section "Emissivity ofCommon Materials.")2. Point the Thermometer at the Press G and aim the laser beam in the center of the area tobe measured.

9 The display shows the measured TemperaturesThe display indicates when a measured temperature reaches thedetection limits of the Thermometer . When you recall an out-of-range temperature, the display shows "Lo" and "Hi" as "---."TemperatureDisplay511 C (951 F)500 C (932 F)-50 C (-58 F)-40 C (-40 F) of range. "Hi" does not of range. "Lo" No. English Instruction SheetPage 8 MaintenanceInstalling the BatteriesRemove the holster before replacing the battery or setting Match the ++++ and polarities of the battery with thebattery case. Do not attempt to recharge the batteries. Do not throw batteries into a fire. Follow local laws or regulations when B indicates battery life remaining.

10 Replace bothbatteries when I starts the Focal LensDo not use solvents to clean the focal lens. Blow off looseparticles using clean, dry compressed air. Gently brushremaining debris away with a camel hair brush or high-qualitylens tissue. The tissue may be moistened with clean the Case and HolsterUse soap and water or a mild commercial cleaner. Wipe with adamp sponge or soft No. English Instruction SheetPage 9 Setting the SwitchesThe switches enable the laser beam and display backlight. Toactivate the laser, press G. The factory settings are in the onpositions.
