Turning On the Instrument To turn the instrument on, press the trigger button. The meter will start up with the last settings that were used. Safety

If the housing is opened, remember that some internal capacitors may still hold potentially lethal voltages even after the device has been switched off. In the event of errors or unusual operation, stop using the device and ensure that it cannot be used until it has been carefully checked out and repaired.

IRT Technology An infrared thermometer detects the infrared radiation that an object emits. The sensor determines how much infrared radiation the object is giving off and the internal microprocessor converts that reading into a temperature reading. Using this method the thermometer can measure an object’s temperature without touching the object. The laser-pointer builds a circle and only used to aim the target. Preparation Do not subject the instrument to extreme temperature variations. This can impair the accuracy of the instrument. Avoid heavy impacts/dropping the instrument. Avoid covering the temp/humidity sensor, infrared sensor or the laser pointers.Operation 22 Testboy

TV 328 Emissivity The emissivity is a value that is used to describe a material's energy radiation characteristic. The higher this value, the higher the ability of the material is to send out radiation. Many organic materials and surfaces have emissivity of approximately 0.95. Attached is a list of the emissivity values of several materials. Metallic surfaces or shiny materials have low emissivity. Therefore, the Testboy

TV 328 is fitted with an emissivity-setting feature. Despite this adjustable emissivity setting feature, we do not recommend taking measurements of shiny surfaces such as stainless steel. You will get more precise measured values if you blacken or tape over the surface to be measured. Measurements cannot be made through transparent surfaces, like through glass for example. You will actually measure the surface temperature of the glass instead. Setting the emissivity To correctly determine the surface temperature of an object, you need to set the emissivity accordingly. The instrument has 3 pre-set emissivity setting: ► High Emissivity (0.95) Concrete (dry), bricks (red, course), sandstone (course), marble, roofing felt, stucco (course), mortar, gypsum, parquet flooring (matte), flooring panels, PVC, carpet, wallpaper (patterned), tiles (matte), glass, aluminum (anodized), enamel, wood, rubber, ice ► Medium Emissivity (0.85) Granite, paving stone, fiberboard, wallpaper (lightly patterned), varnish (dark), metal (matte), ceramic, leather ► Low Emissivity (0.75) Porcelain (white), varnish (light), cork, cotton To change the emissivity setting, press the button until the display shows the correct emissivity degree desired. Temperature measurement To measure the temperature point the IR sensor's opening towards the object to be measured and press the key to measure the temperature. Make sure that the measurement spot size is not larger than the object to be measured. The currently detected temperature is shown in the LCD. To locate the hottest spots of an object, point the Testboy

TV 328 at a location outside the desired area. Then search for the hottest point by moving the detector across the surface of the object in a zigzag pattern holding down the temperature measurement key all the while until you find the warmest spot. After releasing the temperature measurement key the temperature detected will be shown in the display for approximately 25 seconds. During this time, "HOLD" will be shown. The device will switch itself off to save batteries after approximately 25 seconds. Choose the unit you wish to be displayed (°C/°F) using the "AB" key. The laser, when it is turned on, shows the mid-point of the measurement area approximately. This means you can easily make accurate readings.Operation Testboy

TV 328 23 ENGLISH To activate the laser, press the temperature measurement key and the "Down" key until the laser is turned on. The LCD then shows the laser symbol. To turn the laser off again, press the temperature measurement key and the "Down" key again until the laser symbol disappears. When taking measurements in a dark environment you can turn on the background illumination for the display using the buttons temperature measurement and "Up". Surface temperature measurement To measure the temperature of an object, Press the button to enter surface temperature mode. Point the instrument at the object and hold down the trigger. The laser pointers will activate showing the area in which the infrared sensor can see. The display will show the current surface temperature of the object within the measurement spot. After releasing the trigger the display will hold the current measurement.

Highly reflective or transparent surfaces can affect surface temperature measurements. If necessary, cover area with matte tape and allow tape to acclimate to the surface temperature before measuring.

Thermal Bridge Mode Thermal bridge mode compares the surface temperature with the ambient temperature. If the temperature difference is large enough, the LED above the display will change from green to either yellow or red to indicate the possible presence of a thermal bridge. To active thermal bridge mode, press the button to enter thermal bridge mode. Point the instrument at the object and hold down the trigger. The laser pointers will activate showing the area in which the infrared sensor can see. The display will show the current surface Temperature of the object within the measurement spot along with the ambient temperature . After releasing the trigger the display will hold the current measurement. The LED above the display will indicate the possible presence of a thermal bridge. ► Green: Low temperature difference. No thermal bridge detected. ► Yellow: Medium temperature difference. Possible thermal bridge present. Check again at a later time to verify. ► Red: High temperature difference. Thermal bridge detected. The display will flash the surface temperature icon.

TV 328 Mold Warning Mode Mold warning mode compares the surface temperature with the dew point temperature. Dew point temperature is calculated using the ambient temperature and the relative humidity. If the temperature difference is small enough, the LED above the display will change from green to either yellow or red to indicate the possible presence of mold. To activate mold warning mode, press the button to enter mold warning mode. Point the instrument at the object and hold down the trigger. The laser pointers will activate showing the area in which the infrared sensor can see. The display will show the current surface temperature of the object within the measurement spot, ambient temperature , relative humidity and dew point temperature . After releasing the trigger the display will hold the current measurement. The LED above the display will indicate the possible presence of mold: ► Green: High temperature difference. No risk of mold detected. ► Yellow: Medium temperature difference. Possible mold risk present. Check again at a later time to verify. ► Red: Low temperature difference. High risk of mold detected. The display will flash the appropriate measurement that may be the cause.

Reduce the humidity or increase the ambient temperature if high risk of mold is detected.

The instrument cannot detect mold spores. The instrument only gives an indication that mold formation is possible at the given location.

°C/°F toggle To switch between Celsius and Fahrenheit, hold the button for approx. 3 seconds. Automatic power-off After approx. 25 s from releasing the trigger, the instrument will automatically turn itself off.Operation Testboy

TV 328 25 ENGLISH Size of measuring surface - distant-to-spot ratios (D/S) In order to get accurate measuring results, the object to be measured must be larger than the measuring surface of the infrared thermometer. The detected temperature is then the average temperature of the measured surface area. The smaller the object is the shorter the distance to the infrared thermometer should be. The exact size of the measurement area can be seen in the following diagram. This is also printed on the outside of the instrument.

For exact measurements, the object to be measured should be at least twice the size of the measured surface area!
