Furthermore, handhelds are frequently used by people who need them to do their job, so having a reliable device that you can use daily and still count on is important. Most handheld DMM users pull it out of their bag, take some measurements, then put it away. So it's far more user-friendly to have the auto-power-off function as it does now than not. Also, if you need the backlight THAT BAD for THAT LONG, then your problem is lighting in general, so get a headlamp or work light so you're not probing in the dark. |

If you really want to be a nanny you could implement a feature that enables short backlight time when the battery reaches 30% or something like that. Fresh battery? Backlight stays on if I want it to (long press of backlight button...) Battery getting low? Backlight goes off after 20 seconds. While we're here: That could give us another feature for our meters - display of current battery voltage. Maybe a "remaining battery" display on the bar graph. :popcorn: |

The Low Battery icon will come in when the batteries reach approximately 4.2 V --- End quote --- |

Comments have been made that I could just as easily add a second meter for the second parameter. --- End quote --- The dual display is super handy, especially to see for instance AC+DC and the AC component in one glance. --- Quote --- * Data logging is a feature I would really like. I've read however that Brymen data is really weird, so I'm wondering if I'll be able to get it working on a Linux machine without having to write software myself. --- End quote --- Besides the brymen software (which is not that good), there are at least 2 free 3rd party programs that can log from the BM867/869: TSDMMVIEWER: https://www.ts-software-jp.net/index.html (I think I use this one the most) and Testcontroller (lot of functions): https://www.eevblog.com/forum/testgear/program-that-can-log-from-many-multimeters/ Afaik both can log at 5x/sec in high resolution mode (500k counts) despite the brymen manual saying that update rate is only 1x/sec in 500k mode. The only thing imho missing on the BM867/869 (and also on the bm235) is a good autohold function. And the 9V battery is...meh, but acceptable. For that the BM786/789 is a good alternative as it has a very good autohold, but that has no dual display, no 500k high resolution mode and no logging/pc interface. Especially no logging possibility is I think a missed oppertunity in this day and age for a high spec meter. They gave the BM867/869 that functionality, and they are more or less the same price, so why not in the 78x series?!? |
