I have 3 but one of them needs work. As long as they can run in spec and have repeatability I'm not too worried about age. Have your Brymen BM869s drifted yet at all? Any outstanding bugs/flaws? If you have a set of four, your next task is to make them all agree. :) |

My Fluke 18x measure -50uV to 70uV (new meter lower left). But again, none of my equipment is in cal and I don't track their drift. J-R was also suggesting aligning my BM869s using some of those cheap calibrators. You can read about that here: https://www.eevblog.com/forum/testgear/brymen-bm789-360289/msg5031622/#msg5031622 As far as bugs with the BM869s, nothing off the top of my head. I did change the firmware (IC replacement) on one of them to increase the backlight timer. Hardly a bug. You would need to search my posts. If I ran into a problem or attempted to replicate someone else's test, I would have posted about it. |

I've always wanted a 189 to add to my collection of DMMs. Not that I need it for any practical purposes, I have some excellent meters, many of which are safely tucked away unused. But collecting DMMs has become an obsession/addiction/illness, and the 189 just checks a lot of boxes for me. I hate they discontinued it. Conversely, I have no interest in the 28x series at all, and really fail to see their attraction, the price:performance ratio just doesn't interest me. I'm watching a 189 on eBay now that ends in a few hours -- someone please bid it way up and buy it so I have a good excuse for passing it up. I've bought too damn many DMMs in the past few months. :-[ |

Then again, the one my old friend had given me was owned by a company and assigned to a friend of his who had passed away. This company had written custom software for their field techs that supported this meter. When that company was bought out, the new company continued to support that software. Eventually they could no longer get these meters from Fluke and they changed brands. So maybe it wasn't that there was a lack of demand but maybe a part obsolescence. The 189 is just a nice basic meter. Easy to program from the PC. If I had to buy a new meter today, it would still be the BM869s. |
