Start – Begins the desired simulation mode with the stepping
parameters selected.
Mode – Displays the current selected simulation mode. Select
Mode to change.
Low pt – Displays the starting source or simulation value.
Select to enter a value.
Upr pt – Displays the ending source or simulation value. Select
to enter a value.
Steps – Displays the number of steps to take (including the
“Upr pt”). Select to change the number of steps.
Dwell Time – Displays the time delay in seconds at each step.
“Manual” can be selected to enable user to
manually advance to next programmed step.
