External time
Hold is detected during the predetermined time (hold section time) from the point in time when the
SECTION signal is turned on. The hold is released by turning on the T/H signal as a reset
signal.The next detection is started when the SECTION signal is turned on again even if the T/H
signal is not turned on.
The H/E output signal is on between the instant when the SECTION signal is turned off and the
instant when the T/H signal is turned on.
(Example) Ex Time specified section peak hold
t1: A delay time between the instant
when the SECTION signal is inputted
and the instant when the value to be
held is detected
1.0ms (max.)
t2: A delay time between the instant
when the hold section time is expired
and the instant when the value to be
held is determined
1.0ms (max.)
t3: A minimum reset signal width
required for releasing the hold
1.0ms (min.)
Level + time

The H/E output signal is on between the instant when the hold section time ends and the instant
when the T/H signal is turned on.
(Example) Level + Time specified section peak hold
t1: A delay time between the instant
