High resistance leads on meter
Qmavam:
I have a Bryman 235 meter, on the low ohms/beeper setting with the leads shorted, I get a 10Ω to 15Ω reading. If I use shorted dual banana plug I get zero Ωs. If I use one meter lead and touch the opposite banana connector I get 1.8Ω with either probe. I polished up the tips and did lower the resistance down to 4.8Ω to 1.8Ω. But that is inconsistent and depends on how hard I press the leads together. The problem is not broken wires in the leads, (not my first rodeo). Should I just replace the original leads and if so, who sells a compatible set of quality leads.
Thanks, Qmavam

You are looking for Probemaster leads . Google them or search here on the forum. Everyone recommends them and now I do too!

Just curious - are these leads the PVC ones that come with the stock BM235 or the silicone leads that come with the EEVBlog BM235?
Qmavam:
These are the silicone leads that came with the EEVBlog BM235. As far as I have found it seems to be the approximately 1" tips that have the contact resistance. If I just touch them together I can 4.5Ω to 6Ωs, but if i press them together hard and sometimes rotate a bit, I can get it down to 1.9Ωs.

This is actually worse than you get with probably even the crappiest leads you can order from China. It's just not right, I'd contact the dealer for a replacement, if possible.
