content: Hello everyone. I currently have a FLIR E75 thermal camera with two hot dead pixels.Every time I measure temperature, these pixels appear precisely at the boundary between high- and low-temperature areas.When I enable high-temperature tracking, the camera automatically locks onto these dead pixels, resulting in temperature readings nearly 10°C higher than the actual values.Does anyone know how to mask or disable these two dead pixels?

content: On these higher end models usually there is either a menu on the device or external PC software that lets the user "mask" dead pixels..I don't have any FLIR products, as they are either highly restricted (ltd) or ludicrously expensive, so not sure how it works on Flir E75 but its a popular older model, so would guess some of the SW from FLIR would give that ability..On iRay's higher end models, there looks to be a menu, where you have X & Y pixel control and what I guess is a manual UI-menu that can mask/map each single pixels to a user-created map, though nothing I have tried, as it's a relative new product and all the pixels are working well.

content: Dead pixel correction was part of the utilities provided in the Service menu of FLIR cameras back in 2013. Then we had the “E4 upgrade” and FLIR attempts to block such upgrades. Soon after, FLIR removed the Service Menu from their cameras. The Ex0 series still have the Service Menu but I believe it is not present, or not fully populated in the Ex5 series such as your E75. FLIR like to charge customers for “Calibration” of their cameras. Only very high end science cameras seemed to avoid this business practice, but I think even they are limited these days in terms of User calibration.Fraser

content: E75 with FW 6.X.X still have a built-in web interface that allows you to do this.if your firmware is higher, you can roll back it to 6.

content: I am really interested to see that the E75 still has/had a working service menu. Such a useful feature to end users and it can avoid having to send a camera back to FLIR for something minor like a dead pixel map update. FLIR removed the service menu functionality in the later Ex series cameras as a countermeasure to the upgrade attempts.Fraser
