Slew Rate Control
The slew rate control applies to all changes of level whether caused by manual selection, remote
control or the transient generator.
The level change is a linear slew between the two level settings with a slope determined by a
three-position range switch and a single turn control. Read-out is in the units of the mode
selected; the range available in each mode is shown above.
