Say you measure a Delta V 1489 mV and Tref is in an ice bat

Say you measure a Delta V = 1.489 mV and T_ref is in an ice bath at 0 degree C. According to this table, the T junction temperature is about A. 7 degree C B. 17 degree C C. 27 degree C. D. 37 degree C. E. 47 degree C.

Solution

measuring voltage is 1.489mv,from table it is in 30degree row and at 7 degrees column.So temperaturature is 30+7=37 degree centigrades.

answer is C i.e the T junction temperature is 37 degree centigrades
