Bottom Hold
In Bottom Hold Mode, measurements are performed while the timing input
is ON, and the minimum value during the sampling period will be the out-
put 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 sampling period is finished. The
first measured result (A in the figure below) is output from the end of the
first sampling period to the end of the second sampling period. After the
second sampling period, the second measured result (B in the figure
below) is output and the sequence is repeated.
