Fig. 4-12 Line marker display
The line marker operation depends upon the status of which marker is active.
 The x axis normal marker is active (i.e.,
and
 SET lamps are off):
Turn the knob and the x axis delta marker also moves horizontally to right and left in
accordance with the knob action.
The data display portion of the screen displays the read out data of the intersection of
the x axis normal marker with the measurement data curve.
 The y axis normal marker is active (i.e.,
and
 SET lamps are off):
Turn the knob and the y axis delta marker also moves vertically up and down in
accordance with the knob action.
The data display portion of the screen displays the read out data of the intersection of
the y axis normal marker with the measurement data curve. The frequency is not
displayed.
 The x axis delta marker is active (i.e.,
and
 SET lamps are on.):
Turn the knob and only the x axis delta marker moves horizontally to right and left.
The data display portion of the screen displays the difference between “the intersection
of x axis delta marker with the data curve” and “the intersection of x axis normal
marker with the data curve”.
 The y axis delta marker is active (i.e.,
and
 SET lamps are on.):
Turn the knob and only the y axis delta marker moves vertically up and down.
The data display portion of the screen displays the difference between “the intersection
of y axis delta marker with the y axis” and “the intersection of y axis normal marker
with the y axis”.
