Kelvin Double Bridge for Resistance Measurement

Nice reply, and the video may well answer the OP's question, but I was quite a few seconds into watching the video before I discovered that the speaker was attempting to speak English!

I have considerable difficulty understanding people speaking English with accents very different from that of the western US. My hearing is far from perfect, so perhaps others can understand what this guy is saying, but I treated this the about the same way I treat most help desks from India: I tell them I don't understand, and hang up.

Well hopefully this isn't too hard to understand, pretty basic stuff...you really only need to understand about half of what he's saying to get the gist...It's basically just to isolate your ohmic load, to get a precise reading...

Decades had past since I got involved....

The very low ohmic testing is accomplished by pumping small current into the DUT

The test requires the use of testing probes with two paralleled cables /wires terminated in each probe using heavy duty alligator clips ...

These testing probes need to be zeroed first together to negate any resistance that may affect the measurements..

The two initial /final knobs may be intended for the "coarse" and "fine" tuning adjustments of the probes prior to actual testing? It is intended to "Null" your test jig..

All these questions can be answered using the original equipment manufacturer's User Instructions leaflet. If it is not to hand, a simple telephone call to its helpline will precipitate a replacement.

The only thing better is one of those new-fangled telephone thing-a-ma-jigs that spits out the instruction leaflet when the OEM calls it.

I believe this new thing is called a facsimile machine.

But be warned, if you want a banana, and it spits out a picture of one, you still cannot eat it. It takes a really new thing called 3D printer with banana starch and banana oil to print out a banana.
