1-Time Auto Adjust

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. [...]

Adjusting Level & Span Manually

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 [...]

Adjusting Level & Span Automatically

I’m all for using the AUTO adjust feature found on most thermal imagers. That said, it does not mean I can turn my brain off! Many new thermographers believe they can just put their system on AUTO and life will be good. Not true.

AUTO adjusts the span of the image to accommodate all three [...]

Radiometric Temperatures

We’ve spent the past several weeks discussing heat transfer. Radiation is a special mode of transfer because that is the mode by which energy is transferred from surfaces to our imagers.

All of what we see in the thermal image is nearly always based on the amount of radiation emitted from or reflected by the surface. [...]

Heat Transfer by Radiation Part 2

For young children and pets, the first look in a mirror can be very confusing! They may be asking themselves. “Is that real or…?” Most thermographers share a similar exasperation the first time they see a thermal reflection, most commonly from a bright piece of metal. Many go on to understand that reflections are not [...]

Heat Transfer by Radiation

For the past several weeks, we’ve been reviewing heat transfer. Thermographers must understand the basics if they are to successfully interpret their images. Over the next two weeks, we’ll wrap up the review with a discussion of radiation.

Electromagnetic radiation is not only a powerful mode of heat transfer, it is also the way energy moves [...]

Spring is (nearly) here!

Last week we talked about emissivity and reflection, probably the two most talked about issues among thermographers. But that ain’t all we need to talk about! There is a reason engineering heat transfer courses are both long and notoriously challenging. We won’t go that deep into it, but as most of you know, I am [...]

Bundle Up Your Overcoats!

Adding more layers of clothing helps us keep warm in the winter by reducing heat transfer. But Frosty seems to do just fine without any additional layers.

In much of the country, including NC and GA where I just spent a couple weeks, the weather is quite “seasonal,” meaning it is getting cold—right on schedule [...]

Emissivity: Understanding How it Affects Your Thermal Images

I often joke that were it not for emissivity, you’d not need training to use an imager! In our courses we find emissivity is the #1 most confusing issue for people, whether they are engineers, home inspectors or new thermographers. In fact, we all usually have a good laugh that many cannot even pronounce the [...]

Radiometric Measurements---How Thermographers Can Measure them Accurately

In life we often make corrections to our first impressions or first courses of action. Whether we are following directions while driving, stepping on the scale to check our weight or adding cream and sugar to our coffee, corrections are an important part of getting it right! Without them, we don’t get to where we [...]
