Datalog run GPIB code running on Pi3 + E5810A

val3 = 34420A CH1+ and CH2- reading NF742A-1 with I+/I- 100mA from 5720A/H1, Reference 1.00004263 Ω
vbl1 = BME280 in box measure Pressure
vbl2 = BME280 in box measure temperature
vbl3 = BME280 in box measure RH

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 :)
