DESCRIPTION
Any time the ENTER key is pressed, the MX Series returns to
its normal mode of operation. In this mode, changes made with
the shuttle knob, or the data entry keypad will take immediate
effect. The IMMEDIATE mode is useful for slewing output
values such as voltage and frequency and observing the effect
on the load.
When the SET key located in the FUNCTION keypad is
pressed, changes made with the shuttle to any output
parameter will not take effect until the ENTER key is pressed. In
this mode, any changes made to a setup menu will be blinking
to indicate the pending change condition. This mode allows
changes to be made to all output parameters and executing
them all at once by pressing the ENTER key.
