## **Software functions (cont.)** 

**Easy connection function** 

For all the display selections, both energy and power measurements are independent of the current direction. The displayed energy is always “imported” with the only exception of “F” and “H” types (see “display pages” table). 

**==> picture [72 x 72] intentionally omitted <==**

For these latter selections the energies can be either “imported” or “exported” depending on the current direction.
