Damping adjustment

When process input changes exces-
sively, an appropriate damping time
constant should be set.

Input time constant value under
display 

  2 

, time constant can be

changed.

Note)

The above damping constants are
used only for the electronics unit.
The detecting unit has its own con-
stants independent of the
electronics unit (for details, refer to
the data sheet).

Selectable time constant value

No damping ( = measuring period) to
