Besides the conventional Mean (between the start and stop thresholds) and Peak values of
brake effort or deceleration the instrument also measures the Mean Fully Developed
Deceleration (MFDD). This is defined as the mean deceleration between 80% and 10% of
the test speed and is now used internationally as the standard measure of brake performance.
When
MFDD markers
is on, marker lines are placed on the graphs at the 80%V and 10%V
points. These are in addition to the graph marker lines at the start and stop deceleration
thresholds and the external trigger point. Note if brake effort is being measured, the Mean
Fully Developed Effort is determined.
