Figure 21 Frequency Measurement with Explicit Sample Clock
Every time the user reads the data, driver will automatically calculate the frequency

To configure the counter to work in this mode, set JY5211CITask.Mode to
CIMode.Finite or CIMode.Continuous
,
and set JY5211CITask.SampleClock.Source to
CISampleClockSource.Internal or CISampleClockSource.External.
3) Finite/Continuous Mode with Implicit Sample Clock
Frequency Measurement with implicit sample clock is actually using Pulse
Measuement internally. Refer to chapter 4.3.2 for more information.
Every time the user reads the data, driver will automatically calculate the frequency
(
