e. While switching trigger slope between positive and negative, adjust the trigger
hysteresis HYST (fig. 11) on the horizontal assembly A1 until there is 15 mV (6 minor
divisions or 1.5 major divisions) between the starting point of the sine wave for the positive
slope versus the starting point of the negative slope at the left side of the display.
f. Continue switching the slope between the positive and negative as the OFFSET (fig. 11)
on the horizontal assembly A1 is adjusted until the starting point of the sine wave is
centered vertically around the center of the display.
27. Final Procedure
a. De-energize and disconnect all equipment and reinstall protective cover on TI.
b. Annotate and affix DA Label/Form on accordance with TB 750-25.
