0.7 Trigger Source AND/OR Linking
The analog trigger, logic trigger, external trigger, and timer trigger can be
linked with the AND/OR logical operators.
OR: Triggering occurs when conditions for one trigger are met.
AND: Triggering occurs when conditions for all triggers are met.
If the trigger source is set to AND, and the trigger source setting conditions
have already been met when the START key is pressed, triggering does not
occur. When the conditions are not met once but met subsequently, triggering
occurs.
Example The figures below show the difference between the effect of AND/OR linking.
