1.Product function：

CM 3 measuringsystem made by CM - 3 intelligent CNC winch panel, depth measuring instrument,composed of a tension sensor and a mechanical counter. The panel can displaythe depth, speed, tension, tension difference and other parameters, and isequipped with sound and light alarm, speed control and output synchronous depthcorrection function. CM-3 has advantages like high precision, large measuringrange and quick response characteristics. The panel operation is flexible,simple operation and easy to master, intelligent keyboard can realize the depthof zero setting, depth correction coefficient setting, synchronous, super heavyset, tension on the zero tension coefficient setting, overspeed alarm settingfunction; the CM-3 has memory record function when power off.

2.Parameters:

(1) depth display：
