Hi
I have an issue with my solder iron is giving bogus temp readings. So I have it set 350 but it'll read over 400 degrees. Then a second latter it'll read over 500 degrees.
The iron only goes up to 480! AFAIK the temperature sensor and heating element is built into the iron tips.
The tip does get hot just not hot enough. I reckon the microcontroller is shutting the heat off before the tip gets to 350 because of the bogus readings.
I did try a different tip but still the same issue.
I know there's software compensation but it doesn't go that far and the temp is unstable anyway. The software is ran on a atmega 16. I reckon it's using the internal adc on atmega because I can't see any adc chip on the other pcb. There's only 3 ics. One is the atmega and the other two are Darlington drivers for the 7 segment displays at the front.
Please help I spent too much money on this soldering station. When you consider I don't use it much, I would expect it to have lasted longer.
