Result var.: This restriction produces the step level result variable "Grad"which is the lowest gradient
measured during the restriction or the gradient that violated the high limit of the restriction.
Alarms: Gradient high restriction (GHR) and Gradient low restriction (GLR).
Trace: Gradient High and Gradient Low are shown in trace as horizontal lines from the point where
the first gradient was calculated to shut off when Gradient vs. Angle is selected. Restriction
limits must be enabled in the trace form (see View of trace curves).
