Scaling Meter K3TJ

Highly Functional Scaling Meter with
Versatile, Easy-to-read Red or Green
Display

Red or green display color available.
Wide range of scaling settings, including negative

scaling.
Simple average and movement average proces-

sing methods allow 4 s max. to display the process
value, thus reducing display blinking and making it
easier to read the display.

Step display setting adjusts the step of the
displayed rightmost digit to 2, or 5.
It is possible to fix the displayed rightmost digit to 0.

Zero limit setting enables the K3TJ to display zero
for any value less than the set value andisidealfor
water depth display.

Display brightness can be adjusted.
Conforms to the EMC standard EN61010-1

(IEC1010-1).
