One of the easiest, and often safest, types of electrical apparatus to inspect are oil-filled transformer cooling [...]
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 [...]
Let’s face the facts: we are seen as experts. Customers expect answers from us, usually immediate answers. How tempting it can be to make them happy! Armed with our expensive, high-tech tools, it is all too easy to forget we can’t always come up with those answers.
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.
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.
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.
