6. The value of the assumed short-circuit current (Isc) is
shown in the upper part of the display, while the
Line/Loop Z
PE
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
SC
Z
U
I

Z
MEAS
= measured L-L,L-N,L-PE loop impedance
U
NOM
= nominal voltage (depend on the system)
