Hot-Air Rework Station - 303D - Set temp gauge to Fahrenheit

Hey there,

I just picked up one of the 303D rework stations and noticed it’s set to Celsius. Did some googling and saw they are set from the manufacturer to default to C, but didn’t see anything about switching it to F. Is this something that can be done internally or is it like hard-coded to do one or the other (C, in my case)?

It’s defaulted to Celsius, unless you re-program the IC on the board inside…so, for most practical purposes, it’s stuck in C
