The first thing that catches my eye is that this new DMM has 60000 count instead of 500000 count like BM-867/869.
What is the reason to use less than 500000 count chipset for modern DMM?
The first thing that comes up when I see comments like this is how accurate are those 500,000 count hand held DMM's?
The second thing that comes to mind is how often do you really need to resolve to that many digits in a handheld. If I'm about to calibrate something I will use a device (handheld or not) that is designed for the task at hand. More importantly that device will be on some sort of calibration schedule. Most DMM's of the handheld variety are seldom kept on a stringent cal program. That is the case in the hobby world as well as the commercial world.
60,000 counts in a handheld device is a bit of a luxury as in many use cases you can get buy with 3-4 digits easy. In fact sometimes you are better off with fewer digits. Sometimes too much info is a bad thing. By the way I'm not trying to say that high precision and high resolution is a bad thing in a handheld meter, just that for many users it really serves no purpose.
For example at work I'm involved in industrial systems under 600 VAC and similar for DC systems. I can't ever remember needing to know the voltages on such systems beyond the first decimal point. At lower control system voltages under 24 VDC you seldom need to know what power supplies are doing beyond the second decimal point. It is only when you get involved in instrumentation that accuracy and resolution are important for calibration work, at that point you are working with traceable instruments anyways. So 60,000 counts is more than good enough in this context.
