The counting speed is affected by the pulse rise/fall time.
The number of pulses that can be counted depending on the counting speed is as follows. Note that the count may be
incorrect when pulses with long rise/fall time are counted.
The number of pulses that can be counted depending on the counting speed is as follows. Note that the count may be
