Once activated two cross-shaped MAIN CURSORS are positioned on the
waveform. The trace on which the CURSORS operate can be selected in the
SELECT menu. Via the CONTROL menu the two MAIN CURSORS can be
separately positioned horizontally on the waveform. Positioning to the left and to
the right is possible. CURsor 1 and CURsor 2 can not pass each other to avoid
erroneous negative time. Depending on previous measurement selections either
a horizontal dotted line or two so-called LOCATE cursors may also be visible.
The dotted line serves as a ground reference point for certain AMPiitude
measurements. The small LOCATE cursors are placed on the waveform
inbetween the MAIN cursors. Their position is used to indicate exactly where on
the waveform the selected automatic measurement is being calculated. The
result of the cursor measurements are shown on the top text line.

A pre-selection of either AMPLitude or TIME measurements is made via this
