6. The value of the assumed short-circuit current (Isc) is

shown in the upper part of the display, while the

Line/Loop Z

impedance is shown at the bottom of the

display.

Press the SAVE button or touch the icon to save

the measurement (see § 7.1).

The Standard (Std) assumed short-circuit current (Isc)

is calculated using the following formula:

MEAS

NOM

I 

MEAS

= measured L-L,L-N,L-PE loop impedance

NOM

= nominal voltage (depend on the system)
