Ruthenium Oxide RTD thermometer RX-102B-RS

Unlike the other Ruthenium oxide thermometer, this one has 2 leads (instead of 4). We will use this calibrated thermometer first time in Run 77. The thermometer has 40 cm copper leads which can be connected to the tower pins by soldering pins on them. In order to convert this 2-pin for a 4-wire measurement, we solder Pin 1 and Pin 2 to lead 1 and Pin 3 and Pin 4 to lead 2 of the thermometer. This pin setup will not work if we decide to use the fridge wiring which needs V+, I+, I-, V- mapping. We plan to use the 15pin Dsub previously used for Goldman thermometer and hence, can make the required mapping at the warm side for this run since we are using the stripline wiring.

The thermometer is calibrated in the temperature range 20mK to 40K. Since the base temperature of K100 with a tower is around 25mK, we donot need extrapolation of the calibrated points.
