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).

Precautions
Mounting
Recommended panel thickness is 1 to 3.2 mm.
Mount the K3TJ by attaching the mounting bracket supplied as an
accessory from the rear of the K3TJ. Turn each mounting screw
clockwise and tighten it to a torque of 5 kgf$cm (0.49N$m).
Mount the K3TJ as horizontally as possible.
Never use the K3TJ in locations where corrosive gas (particularly
sulfuric or ammonia gas) exists.
Avoiduse of the K3TJ inlocations subject to severe shock orvibra-
tion, excessive dust, or excessive moisture.
Select mounting locations where the ambient operating tempera-
ture is -- 10#Cto55#C.
Others
Whenselecting parameters or making settings,thefrontpanelcovershould be removed. Do not touchpartsother than the DIP switch
andkeys with yourhandorametalobject, especiallywhentheK3TJ
