Datalog run GPIB code running on Pi3 + E5810A

val1 = 3458A measure voltage sourced by 732B Niko
val2 = 3458B measure voltage sourced by H1, 100mV
val3 = 3458C measure voltage sourced by 732Bx xDevs
val5 = 34420A measure 100mV out of K262 10e-3 and H2 10V power
val8 = 2182A measure 100mV out H1 100mV power
vbl = B2987A current out of 16340A 10nA, 100G
vbl3 = B2987A resistance out of 16340A, 100G, 100V source integrated

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 :)
