When measuring through CT( specification is or ), you can set the CT rate(menu " ") by

pressing the "UP" key for 2s; w hen it is wit h other specification( not or ), you can set the display

measuring range(menus " " and " ") by pressing the "UP" key for 2s;

If it is wit h alarm function more, you can set the menus "AH" , "AL" and "dt" by pressing the "DOWN" key.

If it is w ithout alarm function, this operation is invalid; the lamps AH or AL flicker t o indicate the alarm object.
