What would be the best possible measurement accuracy that could be achieved with the E4980A if |Z| = 0.01 Ohms at 60Hz? I went through the equations in the data-sheet and came up with something around +/-20%. This seems excessive since the E4980A has a 0.1 Ohm range. Can anyone else confirm this?

Hi,

Yes, according to thess graphs, I think the error will be near 20%. If I understood the equations, the error would be close to 16.9%. This graph is based on test signal de 1Vrms, cable 0m and time mode at MED.
