(27) Rotate oscilloscope calibrator knob below EDIT FIELD pushbutton to adjust
amplitude for 5 divisions of deflection on TI. If oscilloscope calibrator err display does not
indicate within limits specified in first row of table 6, perform b below.
(28) Repeat technique of (24), (25) and (27) above for settings listed in table 6. If
oscilloscope calibrator err display does not indicate within limits specified in table 6,
perform b below.
