5. Use
TIMEsns
to change the time base and lock on 20 μs/div for the 20 kHz
signal and on 10 ms/div for the 60 Hz signal.
6. Use
mV
RANGE
and
V
RANGE
to select the manual vertical ranging. Set the input A and
B sensitivity range to the first test point in Table 4-4.
The sensitivity ranges are indicated in the lower display edge.
7. Set the 5502A to source the appropriate ac voltage.
8. Observe readings
A, B, C, and D and check to see if they are within the range
shown under the appropriate column.
9. Continue through the test points.
10. When you are finished, set the 5502A to 0 (zero) Volt and Standby.
