F805AT adopts a color LCD touch panel which enables simple and comfortable operation by greatly enhancing the visibility of weight display, various setting values display and status display. It provides high-speed A/D conversion and digital processing capability at an operating speed of 1000 times/sec There are substantial interfaces that allow direct connection to major PLCs including OMRON DeviceNet and MITSUBISHI CC-Link. F805AT, which was developed specifically for weighing systems, is a full-fledged device of an all-in-one type that deserves to be called the top-of-the-line Weighing indicator.


"Load cell" is a sensor that measures a weight or a force.
For the load cells as well as amplifiers and indicators where the load cells are connected to, there are "4-wire type" and "6-wire type". If not wired properly, it may cause not only inaccurate measurements, but also may be affected by the temperature or the cable length.
This time, we will explain the wiring method of both 4-wire type and 6-wire type.

Setting section
Setting method	– Setting by touch panel operation – Setting from host computer via RS-232C is also possible
