Determining the Left Trigger Point
1. On the Film Controls window of SAM, click Position > to advance the film and
determine the “average” low number (indicating the presence of film) on the
left LED.
An example is 120.
2. Subtract the average low number from the highest number you recorded in
step 3 under Recording the Highest Numbers on the LEDs.
An example of the highest number is 800. Subtracting 120 from 800 results in
680.
3. Divide the result of step 2 by 4.
Continuing the example, 680 divided by 4 equals 170.
4. Add the result of step 3 to the average low number determined in
step 1.
The result is the left trigger point. Record this number.
Continuing the example, 170 added to 120 equals 290; 290 would be the left
trigger point.
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.
