4. Detection and calculation
1)The drawing speed of each roller can be defected and displayed,
the line speed is displayed in digital;
2)The length of the finished drawing wire can be measured and
displayed, the expected wire length and the pre-warning can be set
in advance to achieve early warning and stop control at the
expected value.
3)The voltmeter is installed on the electric control cabinet, every
ammeter and other measuring instruments are installed on the main
control cabinet
4)Work time of the device can be measured and calculated , the
records be installed in the control cabinet door.
