Summary
The results imply the following conclusions on the practical utilization of the thermometer, and on the characteristics of the thermometer: Temperatures measured by the CROG thermometer lie within the range from 3.7° to 3.1°K when the supply current ranges from 120 to 990 mA; no changes were observed in the sensitivity of the CROG thermometer over a year's time; the sensitivity of the CROG thermometer over the 3.7° to 3.1°K temperature range is respectively ∼ 6·103 to 5·102 Hz · °K−1; the error in measurements of the absolute values of the temperature on the T58 scale may be small, and can attain values of ∼10−4 to 10−5 °K.
