The test device is used to measure fault loop impedances and network impedances.
The measuring range from 0 to 200 Ω (0.27 Ω to 200 Ω according to VDE 0413 / EN 61557) enables a short-circuit current calculation from 0 to 23 kA.
The METRALINE Z-CHECK enables the following measurements:
- Error loop impedance with short circuit current
- Error loop impedance with short-circuit current - without triggering the RCD
- Line impedance with short-circuit current
- Mains voltage
- Phase detection
