The Tachometer Option

Input Count Division

The tachometer can be programmed to divide the input signal. For example if a signal is coming in at 100 counts per second, the tachometer can be set to look at only every 10th count for a result of 10 counts per second.

Holdoff Time

The tachometer can be programmed to wait for a specified period of time between counts that it will detect. After a count is detected, subsequent counts will be ignored until the holdoff time has passed.
