Datalog run GPIB code running on Pi3 + E5810A

val1 = 3458A measure voltage sourced by FX1
val2 = 3458B measure voltage sourced by FX1
val3 = 3458C measure voltage sourced by FX1 vs 792X , 100mV rng
val5 = 34420A measure 1mV out of K262 1e-4 and H2 10V power
val8 = 2182A measure FX1 vs 792X , 10mV rng
val4 = K2002-4 measure 10V FX4
val6 = K2002-6 measure 10V FX1
val7 = 1281F measure 10V FX5
vbl = B2987A current
vbl3 = B2987A resistance, X16340A 10G, 100V


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 :)
