Test of REF102 N1 output 10V and 3458A@NPLC100 at 10V

TC_BOX is +2.4 ppm/K with trim resistor
TC_BOX is +3.0 ppm/K without trim resistor (shorted)
Absolute measurement uncertainty : 2ppm. ACAL each 0.3 °C


Result CSV-data from HP 3458A

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 :)
