Did it result in a fix of some sort? If I were to order a 121GW right now, can I have confidence it won't have such an issue?

The PCB shim issues was limited to the first few thousands PCB's. That included all the Kickstarter units and a bunch of the first normal production units. All future PCB's have been the correct thickness and the issue was resolved. All units bought today do not have this issue, no one has old stock.

Sorry to ask here, but where to get this shim? I am one of "early kickstarter users", used multimeter very rarely, and i started to get contact issues (i have to press on knob to make multimeter on after changing mode).
Maybe there is some drawings and anything i can do DIY?

Thanks for your assistance.

Surely that means your ground is a high impedance, which means it's not ground at all and could be dangerous if you use it to ground something that needs a ground for safety reasons.

It could be induced voltage from a parallel running cable, however I'd recommend it's investigated by a qualified electrician using an installation tester.

I was forgetting that the 121GW in Low-Z mode is brain dead and shows zero even when there is a low voltage present.
