Using select 1V/div for input A and B.
3. Set the 5500A to source a sine wave, to the first test point in Table 4-5 (NORMAL
output, WAVE sine). Set the 5500A to Operate (OPR).
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.
