(4) Before shutting down the calibrator with the power switch, reduce the
amplitude of vibration to a minimum by rotating the amplitude control knob to the
full counterclockwise position of its adjustment range. You should use the tester
only on a rigid surface, preferably in the same area, each time pickups are tested.
An oscilloscope must be used with the tester in order to observe the waveform being
generated by the pickup.
(5) This completes the operating procedure used with the pickup calibrator.
You are required to calibrate the pickup calibrator. However, since you must use
the procedure outlined in the TB, explanation of the calibration procedure is not
included in this course.
