(1) By setting external input Tare subtraction ON (or with the key on the panel), Net

Set Point 1), Set Point 1 output signal turns ON. (If the comparison inhibit timer is set, the timer
starts.) Set Point 1 valve of the material tank is closed.
(3) When the weighed value reaches (Final - Set Point 2), Set Point 2 output signal turns ON. (If the
comparison inhibit timer is set, the timer starts.) Set Point 2 valve of the material tank is
closed”.
(4) When the weighed value reaches (Final - Compensation), Set Point 3 output signal turns ON,
and if the judging timer is set, the timer starts. The feeding valves are completely closed.
