Type an increment that matches the increment on the seismic section to which you're correlating.

Type the percentage by which to multiply the monitor resolution. Ideally, you need to compare the changes that appear on screen to a fixed measurement by holding a ruler, for example, up to the monitor.

Click the arrow buttons to move the correlation up or down until it aligns with a timing line on the seismic section. The larger arrow buttons move the correlation in larger increments.

Click the arrow buttons to expand or condense the correlation. The larger arrow buttons zoom or unzoom the correlation in larger increments.
