This menu allows for the setting of each of the 8 outputs to be the same as the range limit “Yes” or as set on the previous menus.

See Section 3-5c, Ranges for setting the range limits.

Pressing F5 (More…) changes to the submenu Analog Output Updates per Second.

Pressing the F5 (More…) key changes to the submenu “Analog Output Updates per Second.”

This menu allows for the setting of the update rate for each of the 8 outputs.

In this menu, the parameters for data transfer between the analyzer and exter- nal devices are set. The choices in this menu depend on the configuration of the analyzer. The full specification of the se- rial interface is described in its own man- ual.
