The F2 (Lowz off) function tests the Ghost voltage. When F2 button is pressed, “Lowz on” is
displayed for 5 seconds and “Lowz off” is turned on again. This function measures the Ghost
voltage by lowering the impedance between the L and N terminals for 5 seconds with a low
resistance.
The F5 (TN-net) button is used to change the electrical system on IT-net. Press the F5 key to
change the screen as shown below.
