Resistance-Temperature Conversion Values for Platinum Resistance Thermometer
(3) At 0C. the resistance ratio indicated is 1.000000.
At 1C. the resistance ratio indicated is 1.003982.
the thermometer is correct.
When you multiply the ratio indicated by 25.54900, the product is very near the
value 25.65075. If you didn't know the temperature value (1C.), you could find it
by using the product of the ratio and resistance (ohm) columns.
If the ratio
indicated on your measuring device is 1.1977710 for 50C. (value shown in table 5,
A, for 50C), you
