Saving yet another Fluke 189
daisizhou:
This is what I mean by "imperfect"。Maybe Fluke has outsourced the production to a counterfeit company.Because this instrument has stopped providing after-sales support.
And for your plastic material itself,Looks like it has no flexibility,If you use it for a long time or use it violently,I reckon it will break soon.
So I always recommend repairing it and not replacing it as much as possible.

Fluke wouldn't do any such thing for a product that is out of support, they simply list the part as NLA and tell you they don't have it. The only reason they would continue selling this particular part is that it is still used in some current products. It may simply be updated and redesigned. Perhaps flexible is not better, IDK.

I did read the thread, in part it was a response to what daisizhou said. I was pointing out soldering pins would more likely exacerbate a contamination problem should it exist, rather than directly cause it.
The integrated holsters and low set sockets near the bottom edge on the Fluke 189 aren't my favorite features. Here are some high res photos of the legitimate ones. I'm leaning towards your replacements being chinese knockoffs.
Could be a problem with too flexible sockets when non shrouded banana plugs are used. Less rigidity to prevent the internal contacts moving and transfer stress to solder joint or pin at the pcb.

Cleaning requires great care,I always stress the need for a practical syringe to flush the bottom,and needs to be soaked in ethanol.
Many people don’t understand what I say, so they will fail.
I have a 187 myself, and this is how I repair it.
When I have time I will shoot a video, maybe it will make everyone understand better

Possible. This is now the fifth 18x in my collection. It's the only one with fractured pins. Three of the meters, including this one, were used in harsh conditions. Two of them, including this one have a lot of damage to the plastic and rubber. I would say all five have lived far beyond what I would expect. So from my small sample size, the soft insulators were not much of a problem. I wonder if they helped form a seal around the connector or base.
