Edit: Get gold probes for your Brymen, too. They're only 10 Euros and well worth it.
In my experience, Brymen probes are crap. My Brymen probes has 0.08-0.16 Ω when I bought it with my BM867S and now, after 2-3 years of rare usage at home conditions it has floating 0.2-0.4 Ω. I tried to clean its banana plugs with rubber and ethanol, but it doesn't help. The only way to restore 0.08 Ω is to move and pull the wire near banana plugs, at some position it returns to 0.08 Ω, but if I leave it for some time, it returns back to floating state with 0.2-0.4 Ω. It looks that there is a bad contact between wire and banana plug inside plastic.
For example, just tested them - 0.51 Ω.
I asked Brymen why it happens and they said the following:
For reliability, our test lead design uses mechanical grab to harness wire for connection. Its design does not use soldering. Thus its loop resistance is slightly higher naturally. You may use Relative feature to offset it.
But relative offset button doesn't helps. because probe resistance is randomly floating when you use it. If you set zero on DMM, it will show some offset when you move probes, because their resistance is changed. When it was new, the floating resistance was not a huge, it has floating from about 0.08 to 0.16 Ω and you can close eyes on that. I thought that this is related with temperature dependency. But after 1-2 years it drops to 0.2-0.4 Ω and this is not acceptable.
I tested my DMM with Chinese silicone wires 1 meter each with banana plugs to make sure that this issue is related to the probes and not to DMM. I bought these wires on aliexpress for 8 USD for 5 pieces and they show 0.01-0.02 Ω despite the fact that I bought them about 1 year ago. And there is no floating resistance with Chinese wires, like it happens with Brymen probes.
So I don't recommend these probes, they are not reliable, they have floating resistance issue just out of the box. And this floating resistance will be much worse after 1-2 years, because something is oxidized inside. I'm not sure if this is common issue for Brymen probes or I got just a defective probes, but as Brymen said - they don't use soldering, so at a glance it looks like the reason why they are oxidized.
They are gold plated and it really helps to get contact without pressure on probes, but their internal resistance which is floating when you use probes just make them useless for resistance measurements. You will need to use another probes or wires when you needs to measure low resistnace.
Regarding to the Brymen BM867S, that's my model and this is really good DMM. I can recommend it. But note that there is needs to buy a replacement probes, because branded one which comes with Brymen DMM has a bad quality.
The main difference between BM867 and BM869 is that BM869 has better precision for RMS voltage measurement and works up to 100 kHz. Also BM869 has temperature probes and a little better precision for voltage measurement. Nothig else.
