1. Lock function: makes it easy to read and record, press HOLD button then remove from test solution. 2. 4 Display modes: press SHIFT button: TDS - ppm & °C, EC - μs/cm & °C, TDS - ppm & °F, EC - μs/cm & °F. ...
The paper presents a physical model of the solution space of 2-DOF parallel planar manipulators (PPM), investigates the theorem of the existing revolving input links, and systematically discusses the complete classification of the manipulators. It lays the foundation for future work to study the pro...
