Brymen BM867s ???

<< < (13/17) > >>

J-R:
I don't have the exact answer to your question but this came to mind:
https://lygte-info.dk/info/DMMFrequencyResponse%20UK.html#Brymen_BM829s

The odds are good that the BM867s might be similar to the BM829s (or only slightly better), since the "100kHz AC, AC+DC Voltage Bandwidth" is a bullet point for the BM869s:
https://www.welectron.com/mediafiles/datasheets/brymen/Brymen_BM860s_Datasheet.pdf

There are also quite a few places in the Electrical Specifications section where the BM867s has "Unspec'd" listed, so it seems the BM869s would be the better choice.

Thanks for the input.  They are two resons why I asked for 867s
1. I already have BM869s + USB-PC dongle. I have already write python library for this dongle.
2. Price difference with 869s -160Euro vs 217Euro with all taxes. and shipments.

Just to wake up an old thread. I have one question.
Does somebody measure the AC bandwidth of BM867S?

Datasheet clearly says 100kHz and which ranges it's specified on. I doubt Brymen are making it up.

Thanks for the info
Could you send me an link with datasheet specifying AC BW=100KHz?
==
I cannot find any evidence that AC BW of BM867s is 100KHz.
BM869s is clearly specified until 100KHz
1. EU and global website catalog expelisitly says no for BM867S and yes for BM869s - see page 2 of link below
http://www.brymen.com/images/ProductsList/BM860s_List/BM860s_Catalog.pdf

2. User manual  - page 19 gives unspecified accuracy  for 20KHz...100KHz and 20Hz..45Hz

Oh, no. My bad. 867s is only 20kHz.  :palm:
