Thinned-out Sampling Measurement
Thinned-out sampling mode operates like the linear sampling mode. Difference is
that the sampling interval is not changed in the thinned-out sampling measurement.
So even if both the following two conditions occur, thinned-out sampling mode does
not change the sampling interval, and continues sampling measurement.
• number of sampling points reaches specified NO.OF SAMPLES
• sampling completion condition is not satisfied
Example Operation
This example assumes the following sampling setup:
• INITIAL INTERVAL value is longer than the measurement time
• NO.OF SAMPLES value is set to 10
1. Executes one point measurement, and stores data in memory. Repeats this 10
times every sampling interval (INITIAL INTERVAL setting value) because of
the sampling interval enough longer than the measurement time.
2. If the sampling completion condition is not satisfied after 10 points
measurement, thinned-out sampling mode keeps the sampling interval, and
continues sampling measurement.
To store new measurement data, thinned-out sampling mode discards a data
every couple of nearest data as shown above. Data is updated every
measurement.
