Retest with Susumu resistors on 34470fake module

Datalog run GPIB code running on Pi3 + E5810A

40K resistors on 3458A and C, 7V 34470Fake ref board (Susumu 5ppm/K resistors) on 3458B, 10kCM on K2002 outside of box
Result CSV-data

Workflow:

* RPI accesses DMMs via GPIB and reads data.
* Data is formatted by python script into DSV string and written/append to file on FTP
* DSV-file is visible publicly on https://xdevs.com/datashort/
* Page http://xdevs.com/datalog_mm/ runs D3.js javascript library to read DSV file test.log to input data
* D3.js plots SVG graph online :)
