Finally, do you know how the new electronic meters work?

I've never seen one, but the obvious hypothesis is that they measure the
voltage using a standard digital voltmeter circuit, and measure the current
with a precision 4-terminal milliohm series resistor and another voltmeter.



Here's a pointer to Analog Devices' Tech Notes and Applications on the topic:
