The BENNING IT 105 installation tester is a multifunctional tester for testing electrical installations in com-
pliance with IEC 60364-6 (DIN VDE 0100-600) and EN 50110 (DIN VDE 0105-100) .
The device is intended for the following measurements and tests:
-
voltage, frequency and rotary field (phase sequence)
-
low-impedance resistance (R
-
insulating resistance (R
-
residual current protection devices (RCD
-
loop impedance (Z
-
loop impedance (Z
-
Loop impedance (Z
rent (PFC) and short-circuit current (PSC)
