Because of a thermocouple temperature display failure, the millivolt output of a thermocouple circuit is being converted to a temperature value using conversion tables.
The tables are based on a thermocouple reference junction temperature of 32°F.
The actual reference junction is located in a panel that is maintained at 120°F. Room temperature surrounding the panel is 80°F.
What adjustment must be made to the temperature value taken from the conversion tables to calculate the actual temperature at the measuring tip of the thermocouple?
A. Add 48°F.
B. Subtract 48°F.
C. Add 88°F.
D. Subtract 88°F.
