Hi,

I am running ver. 4.0

Here is the last paragraph on page 19 of Understanding Signals.

√ Move the trigger voltage above 5 V, out of the range of the signal. Notice the
rolling effect. The OPTAscope is looking for a trigger event but does not find
one because you have the Trigger Mode switch set to Auto. This causes the
OPTAscope to automatically trigger even though the input signal never causes a
valid trigger event.

My question is I can not find how to √ Move the trigger voltage above 5 V, out of the range of the signal.

I like to understand everything before I move on.

Thank You,

Jim
