When markers are displayed in the screen, a mark of “*” is attached just before the displayed
item (e.g., f, R,
 , etc.), which is to indicate the value is the one read out by the marker. The
mark “*” is not displayed when frequency seep measurements are being done (See Fig. 4-11
data display examples).

b) How to use line markers
Line markers are displayed in two forms; one is a straight line parallel to the x axis (i.e., y
axis marker) and the other is a straight line parallel to the y axis (i.e., x axis marker). There
are, again, two types of markers for each form of markers: normal markers and delta markers.
The normal marker is displayed in solid line and the delta marker is displayed in broken line.
The table below shows which line markers are active under certain combination of lamp
status (lamps referred here are those of
, and
 SET .). Active markers are those
which move by knob actions.
