Processing trigger -726250108

TM 9-2320-364-34-1

2-8. TROUBLESHOOTING INSTRUCTIONS (CONT).

NOTE

The DDR begins recording data as soon as you see WAITING FOR TRIGGER on the

bottom line of the readout. The DDR has no way of knowing when an operating condition

is going to occur. So, when memory is full, the oldest data is dropped to make room for

new data, in a continuing circular process. The trigger point you select actually determines

how long the recording continues after the trigger occurs.

To find out what happens when the trigger occurs, refer to Step (11) (Processing trigger).

(11)

Processing trigger. While the DDR is waiting for the trigger to occur, the bottom line reads WAITING

FOR TRIGGER. As soon as the trigger occurs (numeric key, any code, or specific code), the bottom line

reads PROCESSING TRIGGER. This notice remains until the DDR has taken sufficient data to satisfy

the trigger point location you selected.

(a)

When the recording is completed, the display will change to permit you to play back the data

recorded.
