List The BCS6400 is capable of storing up to 20 list per channel in the internal memory. Each list can have up to 30 configurable steps. List memory is not sharable across channels; therefore it is important to select the correct channel before editing a list. If all 20 available list are already set, an external list can be imported from a USB, allowing for a larger collection of programmed lists.
List 8.1 List Setup Upon entering the List Interface the last selected list will be displayed. Channel Before editing any parameters ensure the correct channel is selected. List memory is not sharable across channels. Therefore if a list is configured in the wrong channel the other channel will not be able to run said list.
List 8.2 Edit List A list can be edited by inserting, deleting, or replacing a selected step. If a new list is desired the Clear option can be used to delete all parameters at once. List Navigation Use the F1 and F2 softkeys to navigate the set steps. Clear Press the F5 softkey to clear all set steps of the selected list.
List Replace Press the F9 softkey to replace the selected step with a step consisting of the parameters set in the Step Parameters sections.
