CalMachine KX2 Temperature box test, GPIB code running on Raspberry Pi 3 + NI GPIB-USB-HS FC
TC Result = -0.0x ppm/K peakTrim resistor = 470K, B03 modification applied
PID settings: KP=140, KI=0.2, KD=1.2, Max TEC voltage = 10.5V, Max TEC Current = 1A, YSI 44006 current = 100E-6 A
LTZ CM1 KX2 REF = 7.157391 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 :)
