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
