When the internal measurement value (R.V.) falls below the specified trigger level, the
sampling begins. When it goes beyond the trigger level, the sampling finishes. When the
sampling finishes, the internal measurement value (R.V.) minimum during the sampling
period is held as a judgment value (P.V.).
The external input is not required.

• After the sampling starts, if the internal measurement value (R.V.)
becomes [-----] before the sampling goes beyond the specified trigger
level, the sampling is automatically finished and the minimum value dur-
ing the sampling period is held as a judgment value (P.V.).
