CHAPTER 4: USING THE METER

This will display the and the Pt-n(PT numerator) screen.

ZPress ENTER again to change to display the Pt-d(PT denominator) screen.

ZPress ENTER again to select the to Pt-S(PT scaling) value.

The Pt-Svalue can be “1”, “10”, or “100”. Refer to Programming the Configuration Mode

Screens on page 4–10 for instructions on changing values.

Example settings for the Pt-n, Pt-d, and Pt-Svalues are shown below:

•14400/120 V (reads 14400 V): set Pt-nto “1440”, Pt-d to “120”, and Pt-Sto “10”

•138000/69 V (reads 138000 V): set Pt-nto “1380”, Pt-d to “69”, and Pt-Sto “100”

•345000/115 V (reads 347000 V): set Pt-nto “3450”, Pt-d to “115”, and Pt-Sto “100”

Z Press ENTER to scroll through the other CFG parameters.

Z Press DOWN or RIGHT to display the password screen (see Reset Mode and Password Entry on page 4–6 for details).

Z Press MENU to return to the main configuration menu.

Pt-nand Pt-Sare dictated by primary voltage. Pt-dis secondary voltage.

4.3.6Configuring the Connection Setting

Use the following procedure to program the connection (Cnct) setting.
