B.
Next, assume that the temperature for the line is known to be approximately
78 degrees (the VAR 56.3 degree temperature reading verifies that the
transducer output is inaccurate) so a 78 degree temperature will need to be
entered into the computer as a FXD value for the computer to use in its
calculations until the defective transducer can be returned to service.
Examine the current inactive FXD value:
