Notes

1. Heat storage of the anode is calculated based on the anode thermal characteristics.

This determines the X-ray input conditions for subsequent X-ray exposure. For specifying

conditions, contact CETD.

2. To avoid the over-load, the OLP (overload protection) program should be used to restrict the

X-ray input conditions. The X-ray tube assembly should not be used in systems which do not

incorporate the OLP program.

When absolutely impossible to use a system which incorporate the OLP program, contact

CETD for operating procedures.

3. Before you make the OLP program, contact CETD for the detail conditions.
