Airbath test GPIB code running on Pi3 + NI GPIB-USB-HS FC

Mar19 check
F5720/HLK source 100/-100mA currents into JRL 1 Ohm x 4 series network
HP3458ABCD is detector for JRL-1, Delta-3 mode Rcalc = (Vmeas1-Zcorr - 2*Vmeas2-Zcorr + Vmeas3-Zcorr) / 4 / 0.1


Reference levels:
10 VDC;

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 :)
