It's hard to say when it was completely analog before.

I just tested using SCPI with my Fluke 8845A and with simple programming I can get 2 samples per second through SCPI polling. (I realize this seems awfully slow but 1) I'm not an expert yet at utilizing the meter through SCPI and 2) I'm intentionally not placing the measurements into the measurement buffer because then you'll be limited by the size of that memory.)

Anyway, if that's fast enough for you then polling should work for you. You might even be able to use the "program that can log from many multimeters" and avoid having to do any programming:

An update... I figured out how to stream readings indefinitely from the 8845... you use the READ? directive. The Fluke user manual has this to say about measurement rates - the Ethernet interface is capable of transferring 900+ measurements/sec.
Martin72:
I´ve looked in a protocol today with a measurement section copied in there from the recorder, it´s hard to read...
The outputvoltage is plotted as a line, so it´s measured in rms.
Paper stroke is 20mm/h, so the length after 8 hours is 160mm.
If I have the time tomorrow, I would test the hioki if it measure( and displaying) the voltage in rms.
