Datalog run GPIB code running on Pi3 + E5810A

val1 = 3458A measure 11 kOhm S5-61 rear output
val2 = 3458B measure voltage across MM 25K-3 output, 0.4 mA sourced by H1
val3 = 3458C measure 732Bx output
val4 = 2002-4 measure MM2 25000 Ohm VAR output (scale x10)
val5 = 34420A measure 10mV out of K262 10e-3 and H2 10V power
val6 = 2002-6 measure 792X
val7 = 1281F measure MM1 25000 Ohm VAR output (scale x10)
val8 = 2182A measure 10mV out of K262 10e-3 and H2 10V power
vbl = B2987A current out of 16340A 20nA, 1G
vbl3 = B2987A resistance out of 16340A, 1G, 20V 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 :)
