, you can switch the level/span mode, and adjust the infrared image in automatic or manual mode to obtain different image effects. Status Description:

Status Comments Auto level/span Manual level/span Linear level/span In automatic mode, the image is adaptively adjusted according to scene changes for the best image presentation. The temperature scale bar on the right side of the screen displays the temperature range of the current scene, and the endpoints are the maximum and minimum values. 50 Yaoguang S Series Handheld Thermal CameraUser Manual In manual mode, you can adjust the temperature to a value close to that of a specific object in the image, improve the contrast of ROI image, highlight anomalies and analyze small temperature differences. In this mode, distribute from the lowest temperature to the highest temperature evenly (linear color distribution) by changing the color. Method for setting manual adjustment mode. Level adjustment: Move the joystick up and down. Moving up is to increase the maximum and minimum temperature at the same time, and moving down is to decrease the maximum and minimum temperature at the same time. You can also make adjustment by sliding up and down on the touch screen. Span adjustment: Move the joystick left and right. Moving left is to decrease the maximum temperature and increase the minimum temperature, and moving right is to increase the maximum temperature and decrease the minimum temperature. You can also make adjustment by sliding left and right on the touch screen. MAX/MIN: With this setting, you can adjust the level manually. You can also change the upper and lower temperatures individually. 13.3. Temperature Measurement Range The thermal camera can be configured to adjust the temperature measurement range to adapt to scenarios with different temperature distributions. If not adaptive, its required to change the temperature range according to different application scenarios. Note: Adaptive temperature measurement is applicable, but it will affect your imaging.

Touch the analysis tool to move on the touch screen. 63 Yaoguang S Series Handheld Thermal CameraUser Manual 8. Touch and drag the analysis tool to change the size. 14.4. Changing Parameters of Analysis Tool To make accurate measurements, the analysis tool parameters must be set correctly. 14.4.1. Parameter Type The following parameters can be configured. Distance: the distance between the thermal camera and the target. Ambient temperature: the temperature of the air between the thermal camera and the target. Reflected temperature: which is used when compensating for the radiation from the surroundings reflected by the object into the camera. This property of the object is called reflectivity. Emissivity: how much radiation an object emits, compared with the radiation of a theoretical reference object at the same temperature (called a blackbody). The opposite of emissivity is reflectivity. The emissivity determines how much of the radiation originates from the object as opposed to being reflected by it. Atmospheric transmittance: the ratio of the flux of electromagnetic radiation that is attenuated by the atmosphere to the flux of incident electromagnetic radiation. Atmospheric transmittance is an important factor affecting infrared radiation transmission. The atmospheric pressure, humidity and gas density can change significantly in a short period of time where the atmospheric transmittance 64 Yaoguang S Series Handheld Thermal CameraUser Manual over a particular area is greatly affected by meteorology. So, the transmittance will change considerably as a result. The directly way is to measure the reference infrared radiation source such as the standard blackbody at a certain distance with infrared measuring equipment. The measured atmospheric transmittance at this distance is obtained according to the measured value of the blackbody, the radiance of the blackbody and the radiation responsiveness of the infrared equipment. Among the analysis tool parameters, emissivity is the most important parameter that needs to be set correctly. If the emissivity is set to a low value, the reflection temperature also becomes important. Target distance, ambient temperature, atmospheric transmittance and relative humidity are correlated when the distance is large. 14.4.2. Recommended Values If you are not sure about these values, please follow the below recommended values. Distance Ambient Temperature Reflected Temperature Emissivity Atmospheric Transmittance 14.4.3. Change Parameters 2.0m 25 25 0.95 1.0 You can set global object parameters, or modify parameters for each analysis tool separately, such as emissivity, reflected temperature, and distance. NOTE: Setting global parameters is usually sufficient; the two most important parameters are emissivity and reflected temperature. 1.

Applications Introduction 22.1. Smart Power Inspection and Diagnosis With the development of the power system, higher requirements have also been put forward for the safe operation of infrastructure such as power grids and power plant equipment. Major power companies have invested a lot of manpower and material resources in the inspection and maintenance of lines and equipment to ensure the power transmission quality of power enterprises. As an important task to ensure the normal operation of the power system, inspection work can maintain and repair power equipment efficiently, eliminate hidden problems in the operation of power equipment, and fundamentally improve the safety, efficiency and stability of power equipment. Integrating flexibility and intelligence, S series has very high precision and sensitivity, which can measure small temperature differences. So small temperature differences can be found in time during the inspection, reducing the occurrence of abnormal equipment conditions greatly. The functions of intelligent speech recognition and diagnosis make the complex workflow simple, improve the work efficiency, and make S series a good helper for expert-level operation and maintenance. 100 Yaoguang S Series Handheld Thermal CameraUser Manual 22.2. Storage Level Detection There is a temperature difference between the liquid stored in the storage tank and the upper gas. With S series thermal camera, the liquid level of the storage tank can be observed from a long distance, preventing unexpected failures caused by the failure of the liquid level gauge. Storage Level Detection 22.3 PCB Inspection PCB is of small size, high integration and complex structure, and it requires a lot of time and efforts with traditional contact detection. Thermal imaging technology has absolute advantages in troubleshooting faulty circuit boards. With S series handheld thermal camera, you can quickly find abnormally high or low temperature components and judge circuit board failures. PCB Inspection 101 Yaoguang S Series Handheld Thermal CameraUser Manual 22.4 Rotary Kiln Defect Monitoring Rotary kiln is an important equipment for hazardous waste incineration. The interior of the kiln body is made of refractory materials and the exterior is surrounded by steel plates. With the long-term operation of the rotary kiln, the lining material may get erosive and thin, or even fall off, resulting in abnormally high external temperatures. With S series handheld thermal camera, the abnormally high temperature of the outer wall can be found and located, and corresponding measures can be taken to avoid safety accidents.
