Is that M71 and HighVoltage's F732A? They differ by 1.2ppm?

The Fluke 732A (Wulf) was calibrated to 10V +0.6ppm in Stuttgart
The 7000 (M71) was calibrated to 10V +1.7ppm

10V + 0.6ppm + 12µV = 10V + 1.8ppm

The PTB 3458A agreed within 0.2ppm

I would say, that is a very good result

And always remember it's at the faire, 26 +x degC , and all kind of noise around ( I haven't heared any Teslacoils, but was to busy to see much from the faire)  ;)
Was fun, thanks for visiting.

See you next time.

it`s a good question if he can reach the .6ppm when we are brushing the 549 there in <2m distance   :popcorn:
