Temperature box test, GPIB code running on DE1SOC + NI GPIB-USB-HS FC
TC Result = -0.142 ppm/KPID settings: KP=270, KI=0.03, KD=0.05, Max TEC voltage = 10.5V, Max TEC Current = 1A, HEL RTD current = 8.333E-4 A
LTZ VK5RC REF = 7.1341405 VDC;
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/
* D3.js plots SVG graph online :)
