[How do I?] DRO troubleshooting

No, he's on batteries- I don't see how grounding would matter
Possible I suppose but I'm doubtful.
More doubtful than the usual amount- doubtful 2.0

Check Yuriy’s remarks on the linked page in post #7: there is internal grounding in the read head that can go wonky).

Good scales use differential quadrature signalling to provide good noise immunity.
One step down uses simple quadrature single ended TTL levels that are not as immune to noise as above.
IIRC those scales use single ended non quadrature serial data that is quite susceptible to noise, IMO they are not really suitable for an industrial environment. I think you will be chasing your tail until you move to one of the better signalling schemes. I would not be surprised the ones that appear to be working are actually intermittently dropping packets, you just don't notice it.

I haven’t had any issues with my iGaging Absolute Plus scales, and while my home shop is not an industrial environment, I don’t believe @ARC-170 ’s shop is either. There are known issues with the iGaging EZ-View scales, which can be addressed as noted by Yuriy. The EZ-View Aluminum scales are also more vulnerable to how they are physically mounted than are the SS Absolute scales.
