Using Test Targets
To switch Fixed Test Targets on, tick the Display check box. A fixed test
target pattern is displayed flashing on the chart display.
To switch on all moveable test targets, click the On
button. The Target Active check box is automatically
ticked and all moveable test targets are displayed on the
chart display with decaying video trails, showing the
history of the targets' movement.
To display only the moveable test target selected in the target field (e.g.
Test Target 1 ) untick the Target Active check box. Other moveable test
targets are removed from the screen, although their video trails remain.
To switch off all moveable test targets click the Off button.
Changing Moveable Test Target Parameters
When a moveable test target is inactive (Target Active box unticked), its
initial position (range and true bearing) may be changed from the default
parameters.
When a moveable test target is active (Target Active box ticked), its initial
position remains the same while its current position updates. When active
the target's velocity and current position may be changed from the default
parameters.
To change any enabled test target parameters click in the field, the value
changes to green (editable). Move the trackball left or right to change to the
required value, left click in the field to set the new value and exit edit mode.
The three buttons at the bottom of the Test Targets window have the
following functionality:
•
Reset - resets the currently selected test target to it's initial
position.
•
Reset All - resets all moveable test targets to their initial positions.
•
Reset All To Defaults - resets all moveable target parameters
back to their default values.
