Determining the Right Trigger Point
1. On the Film Controls window, click Position > to advance the film and
determine the “average” low number on the right LED.
2. Subtract the average low number from the highest number you recorded in
step 1 under Recording the Highest Numbers on the LEDs.
3. Divide the result of step 2 by 4.
4. Add the result of step 3 to the average low number determined in
step 1.
The result is the right trigger point. Record this number.
Below are examples of determining trigger points. Round to the nearest whole
number.
