With fresh batteries installed, the meter switches ON when the trigger is pulled. Refer to the Maintenance section for Battery Installation instructions. The battery icon provides battery status indication. Replace the batteries as soon as the battery status icon indicates a low battery. Setting Mode The various parameters of the meter are set using the five‐way multi‐switch located below the display. The available parameters are listed below: Flashlight (ON OFF) UV light (ON OFF) Temperature Units (°C °F) Emissivity (0.10 to 1.00) Laser pointer (ON OFF) Max/Min/Avg & Max‐Min (ON OFF) HI LO Alarm (ON OFF) High Temperature Alarm Limit setting Low Temperature Alarm Limit setting Beeper (ON OFF) Setting Mode Overview The Settings switch has five positions to select a parameter, turn a parameter ON or OFF, and to adjust parameter values. Press and release the Measurement Trigger. Press the button left to enter the Setting Mode. The parameter selected will appear in the display. Press the button right to advance to the next parameter. Press the up or down buttons to change a parameter status or adjust a parameter value. Press the button to store parameter changes and advance to the next parameter. Press the button left to exit the Settings mode and return to Measurement mode. Note: If no button is pressed within the APO time the meter will shut down. It may be helpful to extend the APO time when making adjustments in the Settings mode. 4 IR300UV‐en‐GB_V1.0 1/16 EXTECH INSTRUMENTS Setting Mode Detail 1. Flashlight Setting Enter the Setting mode.

Typical setting should be: Laser pointer ON, Backlight ON, Temperature units set as needed, Emissivity set to 0.95, APO (auto power OFF) set to 10 seconds and Flashlight ON if measuring in a dimly lit area. 2. Open the lens protective lens cover by rotating the cover wheel clockwise (facing the lens) until the dot is visible on the wheel. 3. Hold the meter by its Handle Grip and point it toward the surface to be measured. 4. Pull and hold the Trigger to turn the meter on and begin testing in Scan mode. The display will light if the batteries are good. Replace the batteries if the display does not light. 5. Release the Trigger; the reading will HOLD for the time set in the APO setting. The backlight will turn off after approximately 4 seconds. 6. The meter defaults to the programmed conditions in use when the meter was last switched OFF. Laser Pointer The laser pointer circle identifies the area being measured. The size of the area is determined by the distance to spot ratio. Objects outside the circle are not measured. The spot measured should always be larger than the circle for accurate measurements. MAX, MIN, AVERAGE and MAX‐MIN In the MAX MIN AVG mode the meter will record the Maximum value scanned, Minimum value scanned, the Average of the scanned values and the Difference between the Max and Min value. 1. Turn Max Min ON in the settings mode 2. Press and hold the trigger to scan an area. Max, Min, Avg or Max‐Min will be displayed in the lower right display. Press the up button to select the parameter to be displayed. The values will be continuously updated for the length of the scan. 6 IR300UV‐en‐GB_V1.0 1/16 EXTECH INSTRUMENTS UV Leak Detector Inject a small amount of florescent dye into the system under test. The dye/system mixture (refrigerant, for example) will escape and accumulate at all leak sites. Turn the blue UV LEDs on in the Setting mode and scan the system. The residue of the dye at the leak can be easily observed under the UV light. Dyes are available at most HVAC supply outlets. Locating Hot or Cold Spots To detect a hot or cold spot, aim the thermometer at a region beyond the target and then scan the entire region in a slow, up/down motion. Distance to Spot Ratio (Field of View) The meter’s field of view is 12:1 (distance to spot ratio). For example, if the meter is 60cm (24 inches) from the target (spot), the diameter of the target must be at least 5cm (2 inches). Other distances are shown below in the field of view diagram. Note that measurements should normally be made further than 60cm (24 inches) from the target. The meter can measure from further distances but the measurement may be affected by external sources of light. In addition, the spot size may be so large that it encompasses surface areas not intended to be measured. 2.5cm @ 30cm 5cm @ 60cm 10cm @ 120cm 1” @ 12” 2” @ 24” 4” @ 48” It is necessary to ensure that the size of the target is larger than the spot size. The smaller the target, the closer the distance should be. 7 IR300UV‐en‐GB_V1.0 1/16 EXTECH INSTRUMENTS Emissivity Emissivity represents the energy reflectivity of a material. Most organic materials and painted or oxidized surfaces have an emissivity of approximately 0.95. If possible, masking tape or flat black paint should be applied to cover the measured surface. Wait a period of time to allow the tape or paint to reach thermal equilibrium with the surface of the covered object. Measure the temperature of the surface covered with tape or paint only after equilibrium has been achieved. High Low Limits The HI / LO limits provide an alarm when a preset temperature is exceeded. Lens Cover The lens cover protects the lens from dust when the meter is not in use. Always close the cover when storing the meter. Measurement Notes 1. The object under test should be larger than the spot (target) size calculated by the field of view diagram. 2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurements. 3. If an object's surface is highly reflective apply masking tape or flat black paint to the surface before measuring. 4. The meter may not make accurate measurements through transparent surfaces such as glass. 5. Steam, dust, smoke, etc. can obscure measurements. 6. The meter compensates for deviations in ambient temperature. It can, however, take up to 30 minutes for the meter to adjust to extremely wide ambient temperature changes. 7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down motion) until the hot spot is located. 8. When the meter is held at the optimum distance from the target, the single laser dot will appear at the top of the circular laser target. As long as the single laser dot is within the circular laser target, the meter will make an accurate measurement. 8 IR300UV‐en‐GB_V1.0 1/16 EXTECH INSTRUMENTS Maintenance Cleaning To clean the lens use compressed air to clear dust and other particles, then carefully clean with a wet cotton swab. The cotton swab should be moistened with clean water. To clean the meter housing, wipe with a damp, soft cloth. Do not use solvents or abrasives. Do not immerse the IR300UV in water or other liquid. Replacing Batteries When the battery icon indicates a low battery, or when the meter doesn’t switch ON, replace the batteries. The battery compartment lid is located on the rear of the handle. Remove the one Philips head screw and lift the lid off. Replace the three 1.5V AA batteries following correct polarity and then replace and secure the battery compartment lid. Battery Safety Notes: Please dispose of batteries responsibly; never dispose of batteries in a fire, batteries may explode or leak. If the meter is not to be used for 60 days or more, remove the battery and store separately. Do not mix battery types or freshness levels; please use batteries of the same type and of the same freshness level. Never dispose of used batteries or rechargeable batteries in household waste. As consumers, users are legally required to take used batteries to appropriate collection sites, the retail store where the batteries were purchased, or wherever batteries are sold. Disposal: Do not dispose of this instrument in household waste. The user is obligated to take end‐of‐life devices to a designated collection point for the disposal of electrical and electronic equipment.
