METRALINE ZCHECK
Loop resistance measuring instrument
The test instrument is used to measure earth-fault loop impedances and line impedances.
- Table of common protective devices can be displayed
- Digital display, backlit color OLED display, switching between brief and detailed representation
- LED for measurement point illumination
- Patented test probe retainer
- Compact and rugged – for service calls under harsh conditions and laboratory use
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
