Solder can change the reading if you're not super good at soldering... the dissimilar metals can change the voltage read by the sensor.
But all that's moot if the wire is stainless steel. You're not going to get that to work unless you're buying special solder.

Did not know they were that sensitive. Butt joints have to be much worse than solder from a voltage drop/resistance perspective. If they are that sensitive, that would mean the length of cable has to be correct and any "extension" cables would be bad as well.
Soldering anything other than copper or nickel requires special stuff and silver solder or ??? Heck, soldering some types of coated or nylon core copper can be a real PITA.
