Inflection point hold
Detection starts when the SECTION signal is inputted and also the Level Condition is met in
comparison of the Hold Start Level and indicated value. Detection is performed as long as the
SECTION signal is ON.The hold is released by turning on the T/H signal as a reset signal.
The H/E output signal is on between the instant when the hold starts and the instant when the T/H
signal is turned on.The next detection is started when the SECTION signal is turned on again even
if the T/H signal is not turned on.
If you want to perform detection simply by the SECTION signal without using the Hold Start
Level, set the Detection Start Condition to "External Only".
(Example) Inflection point hold
t1: A delay time between the instant
when the indicated value meets the
Hold Start Level under the Level
Condition and the instant when
detection starts.
t3: A minimum reset signal width
required for releasing the hold
1.0ms (min.)
Relative maximum, Relative minimum, Relative difference hold
The way of starting detection is the same as Inflection Point hold.
(Example) Relative maximum hold
t1: A delay time between the instant
when the indicated value exceeds the
Hold Start Level and the instant when
hold is detected.
t3:
A minimum reset signal width
required for releasing the hold
1.0ms (min.)
