MEASURING MODE
!
(4246)
This function is not available unless the STATUS setting was selected in the
OPERATION MODE function (4200) and the status output was assigned a limit value.
Use this function to define the measuring mode for the status output.
Options:
STANDARD
The status output signal switches at the defined switch points.
SYMMETRY
The status output signal switches at the defined switch points, irrespective of the sign. If
you define a switch point with a positive sign, the status output signal switches as soon as
the value is reached in the negative direction (negative sign), see illustration.
Factory setting:
STANDARD
Example for the SYMMETRY measuring mode:
On-value: Q = 4, off-value: Q = 10
➀ = Status output switched on (conductive)
➁ = Status output switched off (not conductive)
!
• SYMMETRY cannot be selected unless the values in the ON-VALUE (4242) and
• If the signs of the two values differ, SYMMETRY cannot be selected and an
