p10919c: Raw voltages from 12 points monitored in measuring
resistances from thermistors.
The 9 equally spaced voltages are measured at the high-voltage end of
the nine series-connected PT-100 thermistors. The larger voltage
difference at the top is across a 320-W
precision (0.01%) resistor, also in the same series circuit. On this scale
the voltages are quite constant with time (5 hours
