Controller;

* High speed A/D conversion and powerful digital processing capabilities of 100.
times/sec. for rapid response to input signal.
* Preset up to 100 coded groups of set point values with sequential running total and three gate feed control for each group.
* Precision head amplifier for outstanding accuracy.
* Low-pass analog filter (2,4,6,8Hz) and selectable digital filterf (2,4,6,8,16,32,64, 128 times per sec.) prevents the influence of vibration.
* Feeding, discharge gate control sequence weighing function initiated by start signal.
* Full digital front panel calibration.
* Secondary calibration with a simple resistor connection.
* All setting values backed-up to non-volatile RAM and C-MOS RAM by lithium battery prevent.
