Calibrating and Adjusting

To adjust the oscilloscope display

5Adjust H.HOLD (horizontal hold) to center the display horizontally.

6 Adjust FOCUS to achieve the best focus.

7Adjust V.LIN (vertical linearity) to position all four corners of the half- bright borders equally.

8Adjust V.SIZE (vertical size) to center the display vertically at the maximum allowable size without losing the half-bright borders.

Because V.LIN and V.SIZE interact with each other, you may need to re-adjust the sizing and vertical centering of the pattern on the display.
