Initializing the recording exposure time selection list (default settings)
1.
Display the window for editing the exposure time selection list (Fig. 5-12).
2.
Clicking [<< Default] displays a confirmation dialog box.
3.
Click [Yes].
Clicking [Yes] resets the [LIST] values to default settings.
Default values are 200 ns, 500 ns, 1,000 ns, 2,000 ns, 5,000 ns, 10,000 ns, 20,000 ns,
50,000 ns, 100,000 ns, 1,000,000 ns, 2,000,000 ns, 5,000,000 ns, and 10,000,000 ns.
To not initialize settings, click [No].
4.
Click [OK].
Save the settings and close the window.
To not save the settings, click [CANCEL].
The range of recording exposure times selectable in [REC] – [EXPOSURE] differs depending on
the recording speed specified in [REC] – [SPEED].
If [REC] – [SPEED] setting is 100 ns or 200 ns
Recording exposure time is fixed and, therefore, not selectable.
If [REC] – [SPEED] setting is 500 ns to 16,666,670 ns
Exposure time settings between 200 ns and 300 ns less than the recording speed setting
([SPEED] setting - 300 ns) can be selected.

Setting External Signal (Trigger) Polarity in [TRIGGER]
– [POLARITY]
This setting is not necessary for the trigger mode [Internal], [External STANDBY],
[External SYNCIN], [R-External STANDBY] or [R-External SYNCIN].
External signals (triggers) can be input in two ways – either as step up (POS) or step down
(NEG) signals. In the [TRIGGER] – [POLARITY] field, select either [POS] or [NEG].
■
Adjusting the Delay Time for External Signals (Trigger) in [TRIGGER]
–
[DELAY]
This setting is not necessary for the internal trigger mode [Internal], external standby mode
[External STANDBY], or continuous external standby mode [R-External STANDBY].
Set the trigger delay in the [TRIGGER] – [DELAY] field. When recording in the external
signal (trigger) mode, the system recognizes the external signal (trigger) input signal after
the delay time specified in [TRIGGER] – [DELAY] has elapsed. Delay times are specified
at 10 ns intervals between 0 ns and 9,999,999,990 ns.
The trigger delay time for the standby trigger mode is about 850 ns (fixed).
