But they don't cost these money, it seems that defective probes with high or floating resistance is a common issue of Brymen brand...
My Brymen probes had such issue just out of the box, and at least 2 people from this thread also reported the same issue.
As I said before, I wrote them email about that issue and they respond that this issue is normal for their production, because they don't using soldering "For reliability, our test lead design uses mechanical grab" and "You may use Relative feature to offset it."...
They propose to use Relative feature because their probes have floating resistance from 0.08 to 1-2 Ω...
That's all what you needs to know about Brymen probes... :--
J-R:
I just tested NINE sets of the Brymen test leads I have and none have that issue. I also checked this thread and only see a report from you and one other person. It doesn't appear to be too common.
'charonme' reported 12 ohms and a lot of fluctuations. That is a completely different scenario and clearly the test leads are faulty/dirty/corroded/etc.
The only test leads I've had this issue was a modular set from Fluke, and they promptly sent me two free sets as soon as I e-mailed them about it along with my serial number.
However, it's true the Brymen leads are targeted at a budget price point, so if you need something better then by all means go buy something else.
Lastly, for measuring low resistances the generally accepted method is via 4-wire Kelvin.
