OUTPUT PULSE WIDTH

DUTY RATIO 50 % (approx.)
The duty ratio remains at 50 % (approx.) even when the output frequency changes.
ONE-SHOT OUTPUT
The output pulse width varies by 10 % of the preset value.
Selectable from 1 msec. up to 10 sec. (50 msec. – 10 sec. for AC/DC switch).
For 10 kHz and a part of 1 kHz ranges, the one-shot output is not selectable. Choose 50 % duty ratio for such cases.
If the preset value is wider than the cycle at 115 % output, this unit does not function properly related ITEM number blinks.)
[Example] 0 % output frequency = 50 Hz
100 % output frequency = 100 Hz
115 % output cycle = 9.3 msec.
The output pulse greater than 9.3 msec. is not appropriate.
