Weird component in load cell Wheatstone bridge
The way to remove this kind of resin is generally with a solvent like methelated spirits and a toothbrush, just takes a long time, have a small jar or similar, place the board in it, and let it soak for a half hour, pull it out and brush away the few 10's of microns of surface material that softened, then put it back in the jar, and repeat

My guess is that component is a laser trimmed resistor, its made of a white ceramic from what I can see, that is likely there factory calibration, to trim the gain of the scale,

The device only corrects its zero every power up, not its gain, so you may have to work out what that resistance was.
