All section
By this method, the hold detection section is specified by the T/H signal.
Detection starts with the T/H signal ON to perform each hold operation.
Control is performed simply by the T/H signal without using the SECTION signal.
Therefore, there are tracking sections and detection sections, but there are no hold deciding
sections.
(Example) All section peak hold
t1: A delay time between the instant
when the T/H signal is inputted and
the instant when the indicated value
is held
Approximately 1.0ms (MAX.)
t2: A delay time between the instant
when the T/H signal is released and
the instant when the indicated value
returns to tracking
Approximately 1.0ms (MAX.)
t3: A minimum reset signal width
required for releasing the hold
Approximately 1.0ms (MIN.)
Note: During the undetermined sections,
the judging output varies with
fluctuations in the input waveform.
However, the H/E output remains
on during the undetermined
ections. Read the judging result
when the indicated value becomes
stable (immediately before the T/H
signal rises).
