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 and is ideal for

water depth display.

Display brightness can be adjusted.

Conforms to the EMC standard EN61010-1

(IEC1010-1).
