4 1 ABOUT THIS INSTRUMENT The Elcometer 214L Infrared Digital Thermometer is an easy-to-use instrument which measures the surface temperature of objects. A laser pointer in the instrument helps the user to aim the thermometer at the object and pinpoint the exact area of measurement. The Elcometer 214L measures the infrared energy emitted by a surface to calculate temperature. Because this is a non-contact method of measurement, the instrument is ideal for electrical and mechanical maintenance, HVAC checks, automotive testing and other applications; anywhere that temperature is a factor. The instrument is small and lightweight and may be carried easily in a pocket. 1.1 Instrument features Precision glass optics for accurate noncontact measurement Temperature range from -32 C up to 530 C (-20 F to 788 F) Switchable between C and F Laser alignment Fast scanning of cold and hot spots Exact measurement of objects as small as 13 mm (0.5 ) at any distance less than 140 mm (5.5 ) Optical resolution 20:1 Angled shape allows simultaneous view of target object and display Backlit display Extremely lightweight 2

5 1.2 What the box contains Elcometer 214L Infrared Digital Thermometer Battery Operating instructions The Elcometer 214L Infrared Digital Thermometer is packed in a cardboard and foam package. Please ensure that this packaging is disposed of in an environmentally sensitive manner. Consult your local Environmental Authority for further guidance. To maximise the benefits of your new Elcometer 214L, please take some time to read these Operating Instructions. Do not hesitate to contact Elcometer or your Elcometer supplier if you have any questions. 2 GETTING STARTED Warning! This instrument is fitted with a Class 2 Laser. Do not point the laser directly at the eye or indirectly off reflective surfaces as this may cause serious damage to the eye. LASER RADIATION DO NOT STARE INTO BEAM CLASS 2 LASER PRODUCT 2.1 Fitting the battery Press and slide down the battery compartment cover at the rear of the instrument. Insert a single 9 V PP3 alkaline battery; take care to ensure correct battery polarity. Replace the battery compartment cover. 3

UP Selects C Toggles laser on/off MAX HOLD MAX 0 0 DOWN Selects F Toggles backlight on/off MODE Toggles between MAX/MIN TRIGGER Press to take a reading 2.3 Switching on/off The instrument switches on when the TRIGGER button is pressed and switches off automatically 7 seconds after the TRIGGER button is released. 2.4 Switching the laser on/off 1. Press and hold the TRIGGER button. 2. Press the UP button to toggle the laser on/off. 2.5 Switching the backlight on/off While the instrument is switched on, press the DOWN button to toggle the backlight on/off. 4

7 2.6 Symbols on the display Backlight, low battery and laser warnings Max/Min reading Temperature and units MAX MAX 0 0 Indicates held temperature (7 seconds max.) HOLD Emissivity 2.7 Selecting units ( C/ F) To select C: 1. While the instrument is switched off, press and hold the UP button. 2. Press the TRIGGER button. The next time the instrument is switched on, the display will show temperatures in C. To select F: 1. While the instrument is switched off, press and hold the DOWN button. 2. Press the TRIGGER button. The next time the instrument is switched on, the display will show temperatures in F. 2.8 Selecting maximum or minimum Press the MODE button to toggle between displaying MAX and MIN on the display. 5

8 3 TAKING A READING 1. Aim the lens of the instrument at the object and press the TRIGGER button. 2. If you are using the laser, adjust your aim until the red spot is on the target. The temperature will be shown on the display. 3. Release the TRIGGER button when you have finished taking a reading. The display will show HOLD, indicating that the temperature shown is the last temperature recorded. 4. The display will also show the maximum or minimum temperature recorded while the TRIGGER button was pressed. To toggle between maximum and minimum, press the MODE button. Seven seconds after the last button press the instrument will switch off automatically and the reading will be lost. 4 MEASUREMENT AREA Your Elcometer 214L measures a circular spot. The diameter of this spot varies with distance from the lens. Distance from lens Spot size (diameter) < 140 mm 13 mm > 140 mm < 1000 mm see diagram below > 1000 mm distance divided by 20 The target area must be at least as large as the spot size. 6 spot size (mm) distance (mm)

9 5 EMISSIVITY The intensity of infrared radiation which is emitted by a body depends not only upon the temperature of the body, but also upon the ability of the surface of the body to emit infrared energy. This ability of the surface of the body to emit infrared energy is characterised by a factor known as the emissivity of the material. 1 Temperature = Infrared energy Emissivity Your Elcometer 214L Infrared Digital Thermometer has a pre-set fixed emissivity value of 0.95; this value is very common for most organic materials and painted or oxidised surfaces. The fixed emissivity value of 0.95 is shown in the bottom right hand corner of the display. 6 HINTS AND TIPS Shiny or metallic surfaces may result in inaccurate readings. To prevent this, cover the measuring surface with either matt black paint or with a suitable tape. Remember to leave extra time for the surface covering to reach the temperature of the body being measured before taking a reading. Infrared thermometers cannot measure the temperature of objects through transparent materials such as glass or plastic. Always keep the lens clear of steam, dust, smoke or other particles which would otherwise cause inaccurate measurement. 7

10 7 TROUBLESHOOTING Code/fault Problem HHH LLL Blank display Laser does not work Above Maximum measuring limit Below Minimum measuring limit Battery may be exhausted Battery may be exhausted Laser is switched off Action Choose target within measuring specifications Choose target within measuring specifications Check/replace battery Check/replace battery Switch on laser (see page 4) 8 STORAGE This gauge incorporates a Liquid Crystal Display (LCD). If the display is heated above 60 C (140 F) it may be damaged. This can happen if the gauge is left in a car parked in strong sunlight. Remove the batteries from the gauge and store them separately if the gauge is to remain unused for a long period of time. This will prevent damage to the gauge in the event of malfunction of the batteries. 8
