Providing the key trigger that starts the data acquisition to the internal memory
This operation is carried out in the trigger wait state. For all other cases, this operation

Note
During the [Trigger] mode, [Full] is displayed when data acquisition to all blocks is complete.
When [Full] is displayed, event data are no longer acquired even if the trigger condition is
met. In this case, save the data in the internal memory to the external storage medium.

On models with the computation option, the confirmation window displays the
following choices : [Mem + Math] (terminate acquisition and all computations),
[Memory] (terminate acquisition), and [Cancel].

function) using the arrow keys and press the DISP/ENTER key to stop the data
acquisition. The icon in the status display section changes to a stop icon.

to a new file.
• Memory write operation can also be started or stopped via remote control or communication
commands.
• The START/STOP operation also starts/stops the report function.
• When the computation is stopped, it is started with the START key.
