1.It is an optional device，by means of a pressure transducer on the injection cylinder，the
actual pressure of the cylinder can be measured，through the high speed closed loop control
inside the control computer，makes the molding process more accurate.
2. CPM， CPP， CPI， and CPD are closed loop control parameters，which have been
adjusted precisely before factory delivery，users shall not change them to prevent affecting
the machine performance.
3.When F3 CURSOR MODE ON，direction key”↑” is for quickly left shift，“←” is for slightly
left shift，“↓” is for quickly right shift，“→” is for slightly right shift. They can be used to move
vertical line to check the position，pressure，speed and time.
4.When F3 CURSOR MODE
OFF，press F6▲ P/V TRANS. POINT move to left，press F7
▲ P/V TRANS. POINT
move to right. It could be used to enlarge and reduce the injection
speed and holding pressure scale.
