20. A: Relative maximum hold B: Relative minimum hold
When the Hold Start Level is detected after turning-ON of the SECTION signal, Relative Maximum /
Minimum hold detection starts.
For the Hold Start Level, Detection Start Condition can be selected.
Also, the value is maintained until the T/H signal turns ON with the hold Detection Start
Condition External Only.
The value is maintained until the T/H signal turns ON.
21. A: Relative maximum hold B: Relative difference hold
When the Hold Start Level is detected after turning-ON of the SECTION signal, Relative Maximum
and Relative Difference (difference between the Relative Maximum and Relative Minimum) hold
detection starts.
For the Hold Start Level, Detection Start Condition can be selected.
Also, the value is maintained until the T/H signal turns ON with the hold Detection Start
Condition External Only. The value is maintained until the T/H signal turns ON.

If there is no relative maximum/

of the sensor input value, resulting in
no hold, both the HOLD and MAX*
status indications will flash.
Also, the H/E signal will not turn ON.

For the Relative Difference, the
indicated value is renewed at the
instant when the Relative Maximum
and Relative Minimum are fixed.
(The sensor input value applies until
the hold values are fixed.)
If there is no relative maximum/
minimum / difference in the changes
of the sensor input value, resulting in
no hold, both the HOLD and MAX*
status indications will flash.
Also, the H/E signal will not turn ON.
* DIF for Relative Difference
