Start with the Gain adjustment and the Response pot fully CCW. The trace will probably
look like Figure 5.1. Turn the Gain CW until most of the instability is gone and the
Tach trace looks like Figure 5.2. Now turn the Response CW until the trace looks like
Figure 5.3. If the Response is turned too far CW the trace will look similar to Figure
5.4. This completes the oscilloscope calibration procedure.
Figure 5.1
Gain set too low.
Figure 5.2
Gain set correctly,
Response not set.
Figure 5.3
Ideal gain setting.
Figure 5.4
Response adjusted too high.
