Product outline

F600AT is a low-priced weighing controller that pursues operability and functions. Adoption of the LCD touch panel that allows easy operation without a manual has realized excellent visibility and operability. This is a practical device packed with the functions required for weighing such as direct connectability to PCs and PLCs including RS-232C, DeviceNet and CC-Link, besides the waveform display function.

Secondary calibration Equivalent input calibration method that allows calibration by simply key-inputting the rated value of a sensor without applying an actual load; Min. calibration resolution at secondary calibration (1/1000 at room temperature)
Setting section
Setting method Set by touch panel operation
Memory of set values ・ Initial values : NOV RAM (nonvolatile RAM)
・ Other values : Lithium-battery-backed-up C-MOS RAM (The memory life is approx. 7 years or more, which varies depending on the operating conditions and storage environment.)
・ Crucial setting values: (calibration, comparison, operational setting, etc.): NOV RAM (Non-volatile RAM)
Protection of set values ・ Setting operation can be prohibited to prevent changes by misoperation.
