p10919d: Voltage differences across the nine thermistors, with an offset of 0.005 V per channel.

The voltages are measured across the nine series-connected PT-100 thermistors. The offsets from thermistor to thermistor, of the order of 0.0001 V or 0.07^oC, seem to be constant over the five hours. A temperature drift of half a degree or so over the five hours seems to have tracked for all the sensors.
