If the timing hold mode is set to peak-to-peak hold, the Unit continues data sam-
pling while the TIMING input is ON.
• When the TIMING input is turned OFF and the measurement mode is selected
using the data input function, the difference between the maximum value and
minimum value of the input data sampled between the leading and trailing
edge of the timing input is stored in the input word as the scaled conversion
data.
• When the TIMING input is turned OFF and the comparison mode is selected
using the data input function, the comparison result flags of the input word are
turned ON or OFF according to the comparison result processed by the Unit.
The Unit stops data sampling during the following periods, The scaled conver-
sion data is "BBBB."


From the moment the Unit is turned ON until the first timing input is turned
ON and OFF.

From the moment the reset input is turned ON until the timing input is ON
and OFF for the first time after the reset input is turned OFF.
