7 Performing the measurement 22 7 Performing the measurement CAUTION High thermal radiation (e.g. due to sun, fire, furnaces) Detector may be damaged! - Do not point the camera at objects with temperatures > 650 °C. Ideal framework conditions • Building thermography, investigating the building shell: Considerable temperature difference between inside and outside required (ideal: ≥ 15 °C / ≥ 27 °F). • Consistent weather conditions, no intensive sunlight, no precipitation, no strong wind. • To ensure maximum accuracy, the camera requires an adjustment time of 10 minutes after it is switched on. Important camera settings • Emissivity and reflected temperature must be set correctly in order to precisely determine the temperature. Subsequent adjustment is possible via the PC software, if required. • When auto-scaling is activated, the colour scale is continuously adjusted to the min./max. values of the current measurement image. This means that the colour assigned to a specific temperature is changing constantly! To be able to compare multiple images based on the assigned colour, scaling must be set manually to fixed values, or must be subsequently adjusted to uniform values using the PC software. 7.1 Saving an image 1 - Press Trigger. The image is automatically saved. Regardless of the image type set, an infrared image is saved with an attached real image. If a higher resolution is required: in the menu under Configuration -> select SuperResolution for four times as many readings.
7 Performing the measurement 23 7.2 Setting measuring functions 1 - Open the Measurement submenu. The submenu with the measurement functions opens: • Pixel mark: o Single point measurement: the temperature measuring point in the centre of the image is marked with white crosshairs and the value is displayed. In saved images, the crosshairs can be moved using the joystick in order to read the value of other measuring points. o Coldspot, Hotspot: the lowest or highest temperature measuring point is marked with blue or red crosshairs and the value is displayed. • Min/Max on Area: o Min/max on area: the minimum, maximum and mean values for a selected area are displayed. o Coldspot, Hotspot: the lowest or highest temperature measuring point within the range selection is marked with blue or red crosshairs and the value is displayed. • Measuring range: choose between two temperature ranges. • Differential temperature: identifies the difference between two temperatures. • External measurement values: select Humidity, Current, Voltage, Solar, Power, None. • IFOV: the IFOV warner shows what can be measured accurately from a specific distance. • Zoom: enlarges the image section (2x, 3x, 4x) 2 - Move the joystick up/down to select the required function and then press OK.
7 Performing the measurement 24 7.3 Image gallery Saved images can be displayed, analysed or deleted. File names Designation Explanation 1 - Infrared image preview 2 IR 000000 SR Infrared image with attached real image Consecutive number Images captured with SuperResolution File names can be changed via the PC, e.g. in Windows Explorer. Displaying a saved image Saved images can be viewed and analyzed in the image gallery. When SuperResolution is enabled, 2 images are saved in the image gallery (an IR image, and an SR image). The high-resolution SuperResolution image is saved in the background. In the status bar, the number of SuperResolution images to be saved is displayed (for example: SR(1) ).

The scale limits can be set within the measurement range. The activated mode is displayed bottom right: A automatic scaling, M manual scaling and S OptiScale (ScaleAssist). Auto-scaling continuously adjusts the scale to the readings presented, and the colour assigned to a temperature value changes. In manual scaling fixed limit values are defined, and the colour assigned to a temperature value is fixed (important for visual image comparisons). Scaling influences the way the infrared image is shown on the display but does not affect the recorded measuring values. With ScaleAssist, a standardized scale is set depending on the inside and outside temperature. Setting automatic scaling 1 - Select the Scale function. 2 - Move the joystick up or down until Auto is selected and then press OK. Automatic scaling is activated. A is displayed bottom right.

M is displayed bottom right. Setting ScaleAssist The ScaleAssist function calculates a display-neutral scale depending on the inside and outside temperature. This scale graduation can be used to detect building defects. 1 - Select the Scale function. 2 - Press OK. 3 - In the mode menu, move the joystick up/down until ScaleAssist is selected.
7 Performing the measurement 29 4 - Move the joystick to the right, select Indoor temperature. - Move the joystick up/down to set the value. 5 - Move the joystick to the right, select Outdoor temperature. - Move the joystick up/down to set the value. 6 - If necessary, move the joystick to the left, back to the mode menu. 7 - Activate ScaleAssist: press Ok. Manual scaling is activated. S is displayed bottom right. 7.6 Setting emissivity and reflected temperature This function is only available if the Image type is set to infrared image. You can choose between user-defined emissivity and 8 materials with permanently set emissivity. The reflected temperature (RTC) can be set individually. Other materials can be imported into the instrument from an existing list using the PC software. Emissivity information: The emissivity describes the capability of a body to emit electromagnetic radiation. This is material-specific and must be adapted for correct measurement results. Non-metals (paper, ceramic, gypsum, wood, paints and coatings), plastics and food have high emissivity, which means that the surface temperature can be easily measured using infrared. Because of their low or non-uniform emissivity, bright metals and metal oxides only have limited suitability for infrared measurement. Highly inaccurate measurements should be expected. A remedy for this is coatings that increase emissivity, e.g. paint or emission adhesive (accessory: 0554 0051), which must be applied to the object to be measured. The following table gives typical emissivities of important materials. These values can be used as a guide for user-defined settings.
7 Performing the measurement 30 Material (material temperature) Emissivity Aluminium, bright rolled (170 °C) 0.04 Cotton (20 °C) 0.77 Concrete (25 °C) 0.93 Ice, smooth (0 °C) 0.97 Iron, emery-ground (20 °C) 0.24 Iron with casting skin (100 °C) 0.80 Iron with rolling skin (20 °C) 0.77 Gypsum (20 °C) 0.90 Glass (90 °C) 0.94 Rubber, hard (23 °C) 0.94 Rubber, soft grey (23 °C) 0.89 Wood (70 °C) 0.94 Cork (20 °C) 0.70 Radiator, black anodised (50 °C) 0.98 Copper, slightly tarnished (20 °C) 0.04 Copper, oxidised (130 °C) 0.76 Plastics: PE, PP, PVC (20 °C) 0.94 Brass, oxidised (200 °C) 0.61 Paper (20 °C) 0.97 Porcelain (20 °C) 0.92 Black paint, matt (80 °C) 0.97 Steel, heat-treated surface (200 °C) 0.52 Steel, oxidised (200 °C) 0.79 Clay, burnt (70 °C) 0.91 Transformer paint (70 °C) 0.94 Brick, mortar, plaster (20 °C) 0.93 Reflected temperature information: Using this offset factor, the reflection is calculated out based on the low emissivity, and the accuracy of the temperature measurement with infrared measuring instruments is improved. In most cases, the reflected temperature is identical to the ambient air temperature. Only when objects with strong emissions at much lower temperatures (such as cloudless skies during outdoor readings) or much higher temperatures (such as ovens or machines) are in proximity to the object being measured should the radiation temperature of these sources be determined and used. The reflected temperature has little effect on objects with high emissivity.
