I have the source keithley 2400 with your four-probe system(conect to PC,and use labtracer 2.0),
and I use this to estimate resistivity of my graphite-polymer composites film.
Is there any standard sample(thin film) which already know its resistivity,and I can use this standard sample to check my instrument is correct or not.
Or there are any calibrate methods for this system?
Another question is that I have used above system to test a Brass film(50 micron-meter) which I know its resistivity(about 6.4*10-7 ohm-cm),
but why it always show Overflow(No mater using panel or labtracer software)? Is this the instrument's limitaion?

I do not know of any standard references for thin film resistivity measurements on our instruments.
