Fluke is not immune to rare firmware bugs and has had some themselves (87V GSM bug???). There have been a number of reviewers and this meter has been out for a couple of years now before this issue was found. I have a BM789 with firmware version 08 and I attempted to reproduce this and I could not with my meter. This means that either this issue does not affect all BM789 meters, or it is an extremely narrow scoped issue. I guarantee that anything with software has edge case bugs that if you search for long enough can be uncovered. The fact that someone can find an obscure bug does not mean that the product is inferior. The company's response though does separate the good from the bad. --- End quote --- Fluke I thought it was a hardware bug a very long time ago, sensitivity to RF and the recall and ferrite bead added. Basic F/W testing includes the boundary conditions. I'm not sure why a range change is even necessary here unless they have a quality problem with the Ohms current source variations and the DMM IC. You'd have to measure the Ohms test current when it's hunting and see it's likely moving around. I'd be upset to spend ~$80 to ship to Taiwan for a F/W update. If a bug is found that includes a safety issue, Brymen would have to eat it. |

Oh wait there's none in North America. --- End quote --- And who's going to pay for all the shipping and time? --- Quote ---Fluke had top quality firmware, it was tested thoroughly, there is no comparison in that regard. --- End quote --- https://www.eevblog.com/forum/testgear/fluke-87v-87-5-87-v-gsm-interference-fluke-says-firmware-flash-fixes-it/ I used to have a 70 series Fluke at work that had an autoranging problem when meanruing mains transformer primaries, it just kept autoranging, displaying nothing. |

Fluke for example very quietly fixed it in production units about 12 months later and made no mention of it at all to new or existing customers. A customer would have no idea what version they were buying. |
