Yes.. agreed.

Would you like to show us any FATAL mistakes that a FLUKE
camera user will make in a home inspection?

Proper training is agreed by everyone... that it taken for granted.

Thank You William! That is the exact point I am making.

Most of the time the home inspector looks at the
pattern and not the temperature. If the temperature is needed, then
an IR thermometer or a FLUKE camera works well within the tolerance
levels of a home inspection.

You did say it but I think you were meaning for the majority of the home scan, but it was just put in in the wrong place. As for the rest I will agree to disagree because I am basing what I am saying off of what I have seen and you are basing it off what you have seen. And what I mean by that is I have seen people dilute temperature measurements on electrical because the don't understand emissivity well. It is one of the more complex subjects of basic infrared theory that I see people struggle with. And this has been those with FLIR Cameras too. So the fatal mistake can happen with them as well if the person if the person does not have a good grasp of it through their training.
No I can not point out a specific incident where this was done with a FLUKE nor can I with a FLIR, but I have seen it as I have trained individuals with both cameras who struggled with the concept. That is the point I was making. I feel it is important for that option to be available on the camera not just the software and I feel it is unfortunate that it is not an option on the TiR. I personally would not recommend someone to buy something that I feel is as important as that. I can and will not in good conscience concede on that point.

Godspeed!

Precisely Charley. Including some emissivity adjustments, different viewing angles, maybe a color palette adjustment, some common sense, a home inspectors intuition, etc, etc, etc. to include accurate temperature measurement of the component. The wires look really warm, but the overall temperature span was very minimal in this image (a dryer circuit in a cool basement)

Oh hey Jason. That middle image was taken on the low temperature range (which is the same range that all b-Series cameras have as standard). Even though the specification is 248 it actually goes up to 302.

Please show us ONE example, within the normal home, that a FLUKE
camera would cause FATAL mistakes.?

That is hard to do when I don't own a FLUKE. But I don't quite understand why you don't understand the concept fully. Some day you'll come across a situation like I am talking about I am sure. The next one I do I will take some extra images for ya.

Oh there goes another horse has been beaten to death and another bottle of glue.

No... unfortunately not by everyone.

That's your flag to wave as I never indicated such.

Thank you.

Since you are not a home inspector, then I understand your struggle
to see how we do things. Home inspectors are only required to call
out something for repairs or further examination. They are not required
to perform the same level of analysis as you might expect of your
self.

Do you think a good electrical inspector with a FLUKE TiR could
see this and understand it?

All of us, in this discussion, believe in training... obviously.

You made a wise move to avoid the FLUKE question about
it being FATAL to use it in a home inspection.

On another note what the heck was that guy doing outside of Arc Flash gear and why were the panels open? Most of the guys that we talk to are required to use IR site glasses of one sort or another and adhere to NFPA 70E.

I totally agree. The camera gives one a sense of being able to determine more than one really can.

If I see something (a pattern) I do other testing, using other equipment, to confirm or deny. I never use the apparent temp of the camera as gospel, but back it up with a temp probe. I also use a moisture meter when I suspect moisture.

NEVER rely, totally, on the camera. And always use the brain, which should be full of the proper physics understanding, as well as building science information.

As to camera settings, that is what emissivity charts are for.

Jason-
I was talking about the image below. No NFPA gear needed.


And again this temperature is measured with the standard -4 to 248 range. It tops out at 302.

lol yeah I cannot imagine you running around in Salisbury arc flash gear avoiding the soldering iron explosion. I was refering to your original story about a guy that got hurt while inspecting a high voltage cabinet.
