This time with a multimeter (resistance directly over D-S) and with a transistor tester.

It appears every measurement is flawed, your lab must be jinxed, thats the only explanation.
Get an exorcist, quick!

At this point it's the only explanation. I'd better move already.

It takes a very good multimeter to measures mOhms.
Maybe inject 100mA ~1A thru a power resistor, and measure the mV drop instead ?
