I have a Hakko FX-888, and recently it took a tumble
, and landed on the knob to adjust the temperature. Normally, I just would measure the resistance with my multimeter to find the resistance range and get an idea if it's linear. However, the fall damaged the pot and it just reads open on the terminals. Also it does not have the wiper any more so I can't measure the range.
I tried looking on Hakko's website to find either a schematic or service manual, but no avail. I also looked at alps website to see if I can make sense of the numbering on the side of potentiometer, but they don't seem to line up with any part numbers I see in the PDFs I have found. Does anyone here know what potentiometer the Hakko FX-888 uses?
