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.
