— Prior to performing adjustment, connect one end of the K-type thermocouple (with miniature TC connector on both ends) to the 5520A TC
output, and the other end to a precision thermometer to verify that the source outputs the desired value. Adjust the source accordingly if
necessary.
— To perform the adjustment, connect one end of the K-type thermocouple (with miniature TC connector on both ends) to the 5520A TC
