Sample Hold
In Sample Hold Mode, the measured result when the timing input is turned
ON will be the output value.
Hold Mode starts when the power is turned ON, immediately after chang-
ing to RUN or T Mode, or immediately after the reset input is turned OFF.
The output is held at the maximum output (current: approximately 23 mA,
voltage: approximately 5.5 V) until the first time the timing input turns ON.
The first measured result (A in the figure below) is output from the begin-
ning of the first sampling period to the second sampling period. After the
beginning of the second sampling period, the second measured result (B
in the figure below) is output and the sequence is repeated.

The output is clamped on
the maximum value until

input turns ON.
Outputs A from the first time
the timing input turns ON.
Outputs B from the second
time the timing input turns ON.
