I cannot help for BM867, but I did measurement of BM869S... It is better than specified...

Thanks for the input,
I've just checked one old fluke 187, I don't have such professional setup as yours . I used rigol MSO7054 function generator and manually change the frequencies - same setting as yours 1vpp AC  You BM869 went from 0,707V to 0,6V rns at 280KHz while Fluke went to 0,600V at 174KHz. That said - the flatness on both dmm's up until 100KHz seems similar. Your bm869s seems over compensated arrount 100KHz while Fluke begins smoothly decrease from 92KHz  I'll test my BM869 tomorrow.

Hello,

i just did a quick test with my BM867s and a SDG1032X. Below is the result. I don't know whether the deviation is caused by generator or multimeter since my second multimeter is not here at the moment.

SDG1032X was set to 2,828V peak-peak in order to get approx 1V rms. BM867s was in auto range but remained in 5V range during all measurements.

Will test again when my Fluke multimeter is back to compare results.

For sure that is the BM867s??  Will be an interesting discovery if the BM867s and BM869s are essentially the same in this regard despite Brymen's claims.

If you look at findings so far there is huge difference between Brymen BM869s and  BM867s
