I ran some ring heater measurements this morning. I incrementally increased the requested current from 0mA to 29mA in units of 1mA. The power radiated from the ring scales as the current squared. We were radiating aorund 6-10W at 630mA requested. With these measurements we would've been radiated no more than ~22mW.

The calculated resistance of the ring heater is 33.93 Ohms for Segment 1 and 34.06 Ohms for Segment 2.

There are some offsets and gain settings between the requested and measured currents that I need to fix.
