They have different Distance to Spot(D:S) ratios anddifferent temperature ranges, read the manual for details.The Thermometer is a non-contact infrared instrument designed with low power consumption, which can make the measurements much faster and easier and meanwhile save you amount of time from frequent battery replacement. It can be powered by the battery or the source with USB connected to.This Manual uses UT303A/B/C/D/E as illustration.Contacting Uni-TrendWarningA warning identifies conditions and actions that pose hazards to the user. To avoid electrical shock or personal injury, follow these guidelines:●●●●●●●●●●●●●●●●● Do not point the laser toward anyone's eye or allow the laser to strike the eye from a reflective surface.Before using the Thermometer inspect the case. Do not use the Thermometer if it appears damaged. Look for cracks or missing plastic.Replace the battery as soon as the batteryindicator appears.Do not use the Thermometer if it operatesabnormally. Protection may be impaired.When in doubt, have the Thermometer serviced.Do not operate the Thermometer aroundexplosive gas, vapor, or dust.To avoid a burn hazard, remember that highly reflective objects will often result in lower than actual temperature measurements.Do not use in a manner not specified by this manual or the protection supplied by the equipment may be impaired.To avoid damaging the thermometer or the equipment under test protect them from the following:EMF (electro-magnetic fields) from arc welders, induction heaters, etc; static electricity;thermal shock (caused by large or abrupt ambient temperature changes-- wait for 30 minutes for the Thermometer to stabilize before use;placed on or near objects of high temperature.Table 1 and Figure 1 show various symbols and safety markings that are on the Thermometer and in this manual.Table 1. Symbols Figure 1. Symbols and Safety MarkingsFeaturesThe Thermometer includes:Single Laser Pointer Intelligent USB-PoweredLevel 2 White Backlight(With USB connected,) this feature will be on automatically).Current Temperature Plus MIN, MAX, DIF, AVG Display Functions Adjustable Emissivity Trigger Locked ℃/℉Selectable Tripod mount One 9V BatteryThermometer features are shown in Figure 2.DisplayThe primary display reports the current or last IR temperature reading until the 8-second hold time elapses.Figure 2. Infrared ThermometerThe secondary display reports a choice ofmaximum, minimum, difference between maximum and minimum temperature or average value.You can toggle through the maximum, minimum,difference and average IR temperatures anytime the display is on. The MAX, MIN, DIF and AV temperatures are constantly calculated and updated when the trigger is pressed. After the trigger is released, the MAX, MIN,DIF and AV temperatures are held for 8 seconds.Figure 3. Thermometer DisplayConnect USB cable for supply power to the unit or data transmission with the software;Backlight will automatically turn on;USB portHow the Thermometer WorksInfrared thermometers measure the surface temperature of an opaque object. The Thermometer's optics sense infrared energy, which is collected and focused onto a detector. The Thermometer's electronics then translate the information into a displayed temperature reading which appears on the display. The laser is used for aiming purposes only.Operating the ThermometerLocating a Hot or Cold SpotThe Thermometer turns on when you press the trigger. The Thermometer turns off when no activity is detected for 8 seconds.To measure temperature, aim the Thermometer at the target, pull and hold the trigger. Release the trigger to hold a temperature reading.Be sure to consider distance-to-spot size ratio and filed of view. The laser is used for aiming only.To find a hot or cold spot, aim the Thermometer outside the target area. Then, slowly scan across the area with an up and down motion until you located the hot or cold spot. See Figure 5.Figure 5. Locating Hot or Cold SpotAs the distance (D) from the target being measured increases, the spot size (S) of the area measured by the unit becomes larger. The spot size indicates 90%encircled energy. The maximum D:S is obtained when the Thermometer is 600mm (60 in) from the target resulting in a spot size of 20mm (2 in). See Figure 6.Figure 6. Distance and Spot SizeMake sure that the target is larger than the spot size.The smaller the target, the closer you should be to it.See Figure 7.Figure 7. Field of ViewEmissivity describes the energy-emitting characteristics of materials. Most organic materials and painted or oxidized surfaces have an emissivity of about 0.95.If possible, to compensate for inaccurate readings that may result from measuring shiny metal surfaces, cover the surface to be measured with masking tape or flatblack paint (<150 o oC / 302 F) and use the high emissivity setting. Allow time for the tape or paint to reach the same temperatures as the surface beneath it. Measure the temperature of the tape or painted surface.If you cannot use paint or use tape, then you could improve the accuracy of your measurements with the emissivity selector. Even with emissivity selector, it can be difficult to get a completely accurate infrared measurement of a target with a shiny or metallic surface.The Thermometer allows you to adjust the unit's emissivity for the type of surface before measured.Refer to Table 3. But it is only a typical case. You could base on your own case and materials to have different setting.To adjust values for emissivity, follow the below procedure:1. 2.3.Press SET to select emissivity set up, icon E on the display is blinking. The Thermometer steps throughemissivity set up, trigger lock and switching o C / oF.Press to increase the value by 0.01 or press and hold to access quick setting. The maximum value is 1.00.Press to decrease the value by 0.0 or press and hold to access quick setting. The minimum value is 0.10.Table 3.

But if you are using USB to power up the Thermometer, the Level 2 white backlight will be on automatically.Relatively high emissivity normally means emissivity setting of about 0.95.Relatively low emissivity normally means emissivity setting of about 0.30.When user cannot identify the emissivity of the object Trigger LockSwithingHOLD●●●●Tips:to be measured, user could cover the surface to bemeasured (temperature >150oC) with black electric tape (emissivity of about 0.95). Allow time for the tape to reach the same temperature as the object to be measured. Measure and record the temperature of the tape.Target the Thermometer to the object to be measured, adjust the emissivity setting to make it as the same temperature as the tape. At this time, the Thermometeremissivity setting is close to the emissivity of the object to be measured, measurement could be started.1.2.3.4.Press SET to select emissivity. Press / to select relatively low emissivity for bright contacts, or 0.7mid level for darkened contacts.Press MODE to select MAX.Measure line and load side of one pole without releasing trigger.A temperature difference between the line and load sides of a pole indicate increased resistance of one point and a contactor may be failing.1.2.3.4.5.Press SET and then press / to set emissivity to relatively low for uninsulated connectors or relatively highfor plastic encased relays or for bakelite enclosed relays or insulated connectors.Press MODE to select MAX.Start to scan.Measure the relay casing, looking for hot spots.Measure electrical connections on relay terminals looking for hot spots.1.2.3.4.5.Press SET and then press / to set emissivity torelatively high for paper covered fuse body or insulated connections.Press MODE to select MAX.Scan the paper covered length of fuse.Without releasing the trigger, scan each fuse.Unequal temperatures between fuses may indicate voltage or amperage imbalance.Press SET and then press / to set emissivity to relatively low, for metal fuses and caps and insulated Testing Contactors (Starters)Testing Enclosed RelaysTesting Fuses and Buss Connections6.7.buss connections.Press MODE to select MAX.Scan each end cap on each fuse/Press SET and then press / to set emissivity to relatively low for uninsulated connectors or buss connections or relatively high for insulated connections.1.Scan the conductor, moving toward direction of electrical connector (quick connect, wire nut, buss connection, or lug).2.Turn off heating, cooling, and blower.Press SET to select emissivity. Press / to selectemissivity relatively high for painted surfaces or window surfaces.Press MODE to select MIN when opposite side ofwall is at lower temperature and or select MAX when opposite side of wall is at higher temperature.Measure an interior partition wall surface temperature.Do not release the trigger. Record this temperature as your baseline (or benchmark) for a ìperfectlyîinsulated wall.Face the wall to be scanned. Stand 1.5m away toscan a 5cm spot on the wall.Scan horizontal rows of wall from top to bottom, orhorizontal rows of ceiling from wall to wall. Look for greatest deviations from baseline temperature to identify problems. This completes the insulation test scan.1.2.3.4.5.6. Testing Electrical ConnectionsScanning Walls for Air Leaks or Insulation DeficienciesTurn on the blower (no heat, no cooling) and retest. If test results with the blower on are different than results with the blower off, this may indicate air leaks in conditioned envelope walls. The air leaks are caused by duct leaks that create a pressure differential across the conditioned space envelope.WarningTo avoid injury when testing bearings:Do not wear loose clothing, jewelry, or anything around neck when working around moving parts such as motors, belts, blower, andfans.Make sure an electrical disconnect is within reach and operatingcorrectly and freely.Do not work alone.Press SET and then press / to select relatively high emissivity.Press MODE to select MAX.Enable motor and allow it to reach steady state operating temperatures.Disable the motor if possible.Measure the two motor bearing temperatures Compare the two motor bearing temperatures.Unequal temperatures or a high temperature can indicate a lubrication or other bearing problem that is resulting from excess friction.Repeat the sequence for the blower bearings.1.2.3.4.5.6.7.●●●Testing Belts and SheavesChecking Hydronic Radiant Heat ApplicationsMeasuring Grille,Register,or Diffuser Discharge TemperaturePress SET and then press / to select relatively high emissivity.Press MODE to select MAX.Enable the motor and allow it to reach a steady state operating temperatures.Aim the Thermometer at the surface to be measured.Start recording temperatureSlowly move the Thermometer up the belt toward second sheave.1.2.3.4.5.6.If belt is slipping, sheave temperature will be high from friction.If belt is slipping, belt temperature will remain high between sheaves.If belt is not slipping, belt temperature will reduce between sheaves.If inner surfaces of sheaves are not a true ìVîshape, this indicates belt slippage and will continue to operate at elevated temperatures until sheave is replaced.Sheaves must be properly aligned (include ìpitch & yawî) for belt and sheaves to operate at appropriate temperatures. A straight edge or taut string, can be used to check alignments.Motor sheave should operate at a temperature consistent with blower sheaves.If motor sheave is at a higher temperature at motor shaft than at outer circumference, belt is probably not slipping.If outer circumference of sheave is at higher temperature than sheave at motor shaft, then belt is probably slipping and sheaves may be misaligned.●●●●●●●● 1.2.3.4.Press SET and then press / to select relatively high emissivity.Press MODE to select MAX.To locate radiant heat tubes in floor, temporarily elevate the loop temperature to create hotter spots for identifying tubing runs.Before releasing trigger, press MODE to toggle between MIN, MAX, DIF floor temperatures and record the temperature for future comparison and trending under similar conditions.Radiant heat tubes in the floor will normally run parallel to the outside walls. Starting at the floor wall juncture,scan parallel to the wall while moving into the room away from the wall. Parallel to the outside wall you should find parallel isothermal rows indicating the location of heat tubes below the surface. Perpendicular to the outside wall, you should find rising and falling temperatures at equal distances. High temperatures indicate you are scanning a heat tube beneath the floor surface, low falling temperatures indicate a space between the heat tubes.1.2.3.4.5.Press SET and then press / to select relativelyhigh emissivity.Aim the Thermometer at the discharge air grille,register, or diffuser.Measure discharge temperature.Release trigger to freeze the temperature readingfor 8 seconds and record this temperature.Grille, register, or diffuser temperature should beequivalent to discharge temperature at the airhandler.1.2.3.4.5.6.Remove panels to gain access to coil return bends or hairpins.Press SET and then press / to select relatively high emissivity for copper tube.Start the refrigeration system.Aim the Thermometer at coil turn bends/hairpins.Start recording temperature.Take temperature of each return bend/hairpin.All evaporator return bends/hairpins should be at or slightly above evaporator saturation temperature from the pressure/temperature chart.All condenser return bend/hairpins should be at or slightly less than condenser saturation temperature.If a group of return bends/hairpins do not conform to expected temperatures, that indicates a blocked or restricted distributor or distributor tube.MaintenanceChanging the BatteryCleaning the LensCleaning the HousingTo install or change the 9V battery, open the battery compartment the battery as shown in Figure 2.Blow off loose particles using clean compressed air.Carefully wipe the surface with a moist cotton swab.The swab may be moistened with water.Use soap and water on a damp sponge or soft cloth.avoid damaging the Thermometer, do NOT submerge it in water.●●●Checking for Blockage in Air-To-Air Evaporators or CondensersTable 4.
