Repeat Mode Settings
You can set trigger-action details in the dialog box displayed by choosing the Setup menu and then Trigger.
The settings in the above dialog box use a level trigger to start recording and an external trigger to stop
recording. A 10-second pre-trigger is specified, and recording is done once.
Pre/Post
Select this to enable a pre-trigger or post-trigger. Turn on the check box to enable pre/post trigger. (The
post-trigger is not enabled for stopping recording by operations that use the toolbar or the buttons on the LX
main unit.)）
Start PreTrig
Specify the length of the pre-trigger in seconds or in scan units. To switch the units, click a button on the
right. When 0 is entered, Timeout is disabled. Set a value that does not exceed the upper limit of the
pre-trigger setting.
The upper limit of pre-trigger setting can be calculated as follows.
Upper limit value (scan)
= (63MByte x 0.6) / [((Number of analog input ch. + Number of tachometer Input ch.) x AD width)]
Upper limit value (sec)
= Upper limit value (scan) / Sampling frequency (Hz)
※ 63MByte x 0.6: Memory capacity used for pre-trigger is 60% of 63Mbyte.
The memory capacity used for pre-trigger can not be increased by adding optional expansion
memory.）
※ AD width 2 for 16 bits A/D, 4 for 24 bits A/D
Number of tachometer input channels: use "2" in 16 bits mode, "2" for 32 bits/1 channel mode, or "4" for 32
bits/2 channels mode. In 24 bits A/D: not available in 16 bits mode, "1" for 32 bits/1 channel mode, or "2" for 32
bits/2 channels mode. Tachometer input channels are available for LX-120 only.
