A normal trace display will be ± 1 divisions from the red reference line while under calm sea conditions and
with DishScan Drive turned off. See example below
The Cross Level display will decrease (plots below red line) as the antenna requires drive to the left and
increase (plots above red line) as the antenna requires to the right.
Example: The antenna pictured in the screen capture below is imbalanced so that it is “Right Heavy”. The
CL trace is plotting above the red reference line (indicating that drive CCW is required to maintain a
90°Cross-Level position).
The Level display should decrease (plots below red line) as the antenna requires drive forward (Up in
elevation) and increase (plots above red line) as the antenna requires drive back (Down in elevation).
Example: The antenna pictured in the screen capture below is imbalanced so that it is “Front Heavy”. The
LV trace is plotting above the red line (indicating that drive CW is required to maintain the Current elevation
position).
