Refer to the drawing of a simple thermocouple circuit (see figure below).
A thermocouple temperature indication is initially 410°F with the reference (cold) junction at 125°F.
An ambient temperature decrease lowers the reference junction temperature to 110°F, while the measuring junction temperature remains constant.
Without temperature compensation for the reference junction, the new thermocouple temperature indication will be…
A. 380°F.
B. 395°F.
C. 410°F.
D. 425°F.
