The minimum value of the specified period (sampling period) is held as a judgment value
(P.V.).
 When “Level” is set for " 6. Timing Input" (page 4-23)
The sampling period is from the falling edge of the timing input to the next rising edge. On
the rising edge, the internal measurement value (R.V.) minimum during the sampling period
is held as a judgment value. When the timing input is turned OFF, the next sampling period
begins.

 When “Edge” is set for " 6. Timing Input" (page 4-23)
The sampling period is from the rising edge of the timing input to the next rising edge of the
timing input. On the rising edge, the internal measurement value (R.V.) minimum during the
sampling period is held as a judgment value. When the timing input is turned ON, the next
sampling period has already begun.
