FC400DAC High-speed sampling & high resolution

The high-speed A/D converter enables the faster and more accurate weighing.


Various features

■ High-performance filter: 
With the powerful filter against noise, high-speed an high-accuracy weighing can be achieved. 


■ Auto filter adjustment:
The filter is automatically adjusted to reduce the noise when the auto adjustment key is pressed. 


■ Equivalent input calibration:
Theoretical calibration can be performed easily by registering the capacity and rated output of the load cell(s).


■ Multipoint calibration (linearization):
Three additional points can be defined in the middle between zero and span to improve the linearity.


■ Input conversion value display :
The output signal level of the connected load cell can be displayed in mV/V/ for monitor purpose.


■ Basic weighing process control function:
Sequential control can be performed without external devices like PLC.
