Three selections are available to the user for setting analysis point No. 1:
1. PERCENTAGE OF STRK
2. DISTANCE FROM CLOSE
3. CONTACT #1
a. Percentage of Stroke
Percentage of stroke is the distance based upon the percentage of the total breaker’s
stroke distance. The distance is always measured from the starting point at the fully closed
position of the breaker contacts. See appendix A for more detail.
b. Distance From Close
Distance from Close range is selectable from 00.0 inch to 99.99 inches or from 0.0
centimeter to 99.90 centimeters. Again, the distance is referenced from the contact's
closed position.
See Appendix A for more detail.
c. Contact Point #1
Contact point is the distance from the contact's closed position to the point where it is in
transition from the close-to-open or the open-to-close position. Contact channel #1 will be
used for the selection.

There are three selections for analysis point 2:
1. PERCENTAGE OF STRK
