-273 C with lepton 3 #18

im useing a lepton 3 on the t cam mini rev2, i can get a good thermal image but the S & M1, 4 temperatures gives me a fixed -273 Celcius valeu, Is this because the software is made for the lepton 3,5 ? If so will be there a lepton 3 FW choice or does this need a hardware mode to ?

Hello technoturk,

I think you must be using a pre version 2.0 Desktop app that doesn't have support for Lepton 3 (that was added to the Desktop app in version 2.0). In the 2.0 application I suppress all temperature display and disable the spot and markers.

This is because the Lepton 3.0 does not support radiometric data output (which is why I originally didn't support it). So it is not possible to easily extract temperature data from its output.

I added support for the 3.0 so people who had them laying around could at least get good images out of tCam-Mini and the software wouldn't malfunction (as you are seeing).

I realize this isn't probably the answer you were hoping for but I hope it explains what you are seeing.
