I mean measurement conditions specific for test leads, it's not defined.
Anyone measure it in way they wanted and this make any information from that publications non usable to others.
I measure it not in series connection to avoid any inaccuracy from the contact resistance.

You can use both leads (red+black) in series and touch the probes together in the middle to simulate that.   :-DMM

Crumble:
I got the "Fluke" leads in too, and they seem quite good. I do not have a 4-wire capable meter, but the AN8008 shows them as being about 0,04\$\Omega\$ when shorted, making them half of that each, which is quite good. The leads do seem to contain some surface corrosion or plastic residue, because the sides make only intermittent contact upon touching. There's quite some "scrachyness" to them in continuity, even after cleaning with acetone and then contact spray. Visually I don't see anything obvious though. They do have a nice finish though, and they do "work". The CAT IV safetycaps have a very loose fit though (but I won't be using those, I'm not an electrician).

I don't remember seeing much in the standards about the test leads.  Maybe they have their own standards.  I ran some destructive test on several test leads some time ago where I was applying a stepped constant current through them and comparing the results.  I recently ran the leads supplied with the ZT102/AN8002 and show how they compare with the other leads I have looked at.   If I continue to look at test leads, I will just follow this same procedure.   

It would be nice to do some other tests like bending the leads in a tight radius until they fracture, a pull test, maybe a material and plating type/thickness.

HELP MY RESEARCH!

i am looking for some 8001 / 8002 eeprom dumps from  meters that do NOT have frequency&duty cycle on the volts range.

i want to see if it's an undocumented bit in the eeprom.
if it is, we can enable it on other meters too - like UT-210e for example!
