With the 1-Touch Level/Span function, simply touch the screen to select a small focus area on a thermal image, and the camera automatically adjusts the level and range, according to the thermal contrast of the selected area. The result: time-saving manual adjustments. Touch the touchscreen to select an object or area of interest, which is then displayed surrounded by a circle. The camera will then automatically reduce the range to clearly represent the temperature range and level visible inside the circle, enhancing the level of detail in the thermal image by highlighting problems.
This makes it possible to focus on anomalies and interesting details. The 1-Touch Level/Span function allows you to leave out any uninteresting parts of the image by reducing the range (see image).
Let's say you want to know the temperature of the hot spot, but you're not interested in the temperature of the sky. If you touch the transformer area on the screen, a circle appears around the selected area and the temperature range adjusts to highlight the lowest and highest temperatures in the circle (figure B). The contrast of the thermal image increases, enhancing the level of detail in the image and making it easier for you to locate an anomaly, or even identify faults, especially when small temperature differences are significant.
The 1-Touch Level/Span function is also useful in building diagnostics and electrical inspections, particularly for a target whose temperature is extremely distant from that of the background, such as a boiler or air conditioner. The presence of two opposite temperature extremes in the scene, that of the target and that of the background, forces the camera to widen the range of the thermal image, reducing contrast.
Recognizing the usefulness of the 1-Touch Level/Span function, Flir engineers have incorporated it into the new T500-Series professional thermal imaging cameras. The T500-Series cameras, which combine the T530 and T540 cameras, are designed for thermal imaging specialists and IR service consultants in the power generation, electrical distribution and manufacturing sectors. They prioritize resolution, speed and ergonomics. These thermal imaging cameras feature 180° rotating optics and a bright LCD screen, all in a compact format. They give specialists the tools they need to carry out complete inspections in difficult conditions, especially when equipment is out of sight or difficult to access.
