(3) Press oscilloscope calibrator VOLTAGE pushbutton to illuminate green LED.
Set oscilloscope calibrator output to 10 mV and output frequency to 1 kHz.
(4) Adjust A TRIGGER LEVEL and POSITION controls, as necessary, to view
(5) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
obtain 5 divisions of vertical display. Oscilloscope calibrator err display will indicate
within limits specified in table 3.
(6) Repeat technique of (4) and (5) above for settings listed in table 3. Oscilloscope
calibrator err display will indicate within limits specified in table 3; if not, perform
adjustments list in table 3.
