3. Set the 5500A to source an AC voltage, to the first test point in Table 4-4
(NORMAL output, WAVE sine).
4. Observe the Input A and Input B main reading and check to see if it is within the
range shown under the appropriate column.
5. Continue through the test points.
6. When you are finished, set the 5500A to Standby.
