If you’ve had Level I Thermographic Applications training course you most likely heard the mantra of “Focus First!” from your instructor, and with good reason! Of all of the camera settings that can be adjusted by the camera operator, focus is by far the most important. Focus is essential to both image quality and temperature [...]
Regardless if you’re inspecting buildings, roofs, or electrical or mechanical apparatus, when you have an abundance of air movement across a surface, there is an increase in heat loss or gain on that surface from convective cooling or heating.
Convective cooling is often discussed in many applications of thermography. Often the result is cooling of anomalous [...]
A new generation of tools with next generation performance
This trio of new Fluke infrared cameras is equipped with LaserSharp™Auto Focus. For consistently in-focus images. EVERY.SINGLE.TIME.
Every infrared camera user knows that without an in-focus image temperature measurements may not be accurate and it’s much easier to miss a problem. LaserSharp™Auto Focus tells you exactly where you are focusing. This is point-and-shoot-and-get- it-right every single [...]
I’ve been working on a project this past week with a couple of young people. I’m impressed with two things. First, they have more energy than I have. Second, I have more experience than they have. While energy is great, relying on experience often means I know how to do things “smarter,” using less energy. [...]
Some problems don’t necessarily “shout” at you. The increase in temperature of this surge protection device in a substation is only a few degrees warmer than normal. Seeing the signature required adjusting the imager skillfully. Understanding the device could fail at any moment required additional background knowledge and clear [...]
Last week I talked about the value of following professional standards. Not only do they lay out the best “recipe” for success but standards are also widely accepted as “collateral” in most industries where we work. By following standards, your work will immediately gain credibility.
Section 14 of ASTM C-1153, Standard Practice for Location of [...]
Last week I talked about how to move yourself and your imager into the best position to get good thermal data. Another big part of being successful is understanding and following professional thermography standards. Like a good time-tested recipe, these help us get high quality, consistent results.
As I’ve said before, I’ve made plenty of mistakes [...]
After years of working with new thermographers in our training classes, I’ve learned a lot about how people learn. First, we never get it right the first time! Don’t worry about making mistakes, in fact, it is important to make them. But it is also equally important to learn from them. In class we let [...]
Last week we discussed how to adjust level and span manually. Sometimes this can lead to a lot of “button pushing!” It is not a big deal – just one of life’s little aggravations. Thankfully, many models of Fluke imagers have a very helpful solution: 1-TIME AUTO ADJUST.
Both images were taken using AUTO adjust. [...]
Last week we discussed how to adjust level and span automatically and when that feature is best used. While using AUTO can be very convenient in many situations, you’ll quickly find times when MANUAL adjustment is essential, either to getting the best image or understanding what you are seeing.
Use AUTO adjust to get “in [...]
