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).

crease automatically if the Down Key is
pressed for 1 s or more.
