Technical characteristics
The measuring range of 0 to 200 Ω (0.27 Ω to 200 Ω per VDE 0413 / EN 61557) permits calculation of short-circuit current from 0 to 23 kA.
The following measurements can be performed with the METRALINE Z-CHECK:

Fault loop impedance with short-circuit current
Fault loop impedance with short-circuit current without tripping the RCCB
Line impedance with short-circuit current
Line voltage - Phase detection
