Hi @Commanderfranz I can't find any specification for maximum temperature for AD2. I suppose we can consider the common 0...40*C standard. The devices are preheated for manufacturing test and calibration procedure, which is performed at normal room temperature (25*C), having the internal device temperature around 45*C The temperature drift of the scope reading is about (40 ppm/*C). In case you want better precision the device can be recalibrated using the WF application. Before thi
