Hi 8,

Klaus - In case you missed it, I basically asked what the kit would do when it got too hot... throw an error, or just display inconsistently and let you know it's overheated. If it does the former, can you possibly put in a change to do the latter?
The unit throws an error. The reason is that when the sensor housing gets too hot, the parasitic resistance coupling between the sense-cell and the pump cell gets so big that the processor can no longer reliably distinguish the sense-cell signal. The LM-1 measurement method is not an analog measurement of a pump current, but a thresholded measurement for sensor output pulse timing. If these pulse can no longer be distinguished, the unit throws an error.
