3-10. AC Current
Use a Fluke 5790A or equivalent with the appropriate precision shunts and adapter to
measure the 5500A output. Refer to the 5790A Operator Manual for operating
instructions and connections. Enter into the 5500A each of the measured values listed in
Table 3-5 when prompted to do so.
