5. Press , , use the RPG control to set the
Hi-level to its maximum (0V).
6. Press , use the RPG control to set the clock amplitude to its
maximum level (1 V).
7. Press Autoscale on the scope and select the DELTA V markers ON.
8. Set Marker 2 to the trough of the signal and Marker 1 to the peak of the signal. Read
Marker 1 as the “High Output level” and 0V as the “Maximum amplitude”. Enter these
values in the Performance Test Record.
9. Press , use the RPG control to set the Hi-level to its minimum
(−1.5 V).
10.Press , use the RPG control to set the clock amplitude to its
minimum level (500 mV).
11.Set Marker 2 to the trough of the signal and Marker 1 to the peak of the signal. Read
Marker 1 as the “Low Output level” and 0V as the “Minimum amplitude”. Enter these
values in the Performance Test Record.
12.Check that the amplitude and offset can be adjusted as shown in Table 11-3. Greater
reading accuracy will be achieved if the channels are viewed one at a time.
