K Constant

The K constant is used to convert the outputs of the displacement sensors
into actual figures. The setting of K constant is available only when the K3TS
is set to

on operating parameter 1.

Setting range

RUN mode

Press and hold the Level Key for 2 seconds to select level 1.

Setting level 1

Press the Display Key.

LED Models

Thumbwheel Switches Models

Press and hold the Level Key for
1 second to return to RUN mode.

Press the Shift Key several times to display

Press the Up Key and Shift Key to set K constant. Press the Display Key to write the value.
