Loop resistance measuring device. The test device is used to measure fault loop impedances and network impedances. Table of common protective devices can be displayedDigital display, color backlit OLED display, switching between short and detailed displayLED for measuring point illuminationPatented fixation of the measuring tipsCompact and robust - for rough service operations and laboratory operation. The measuring range from 0 to 200 (0.27 to 200 according to 0413 / EN 61557) enables a short-circuit current calculation from 0 to 23 kA.The METRALINE Z-CHECK enables the following measurements:Fault loop impedance with short-circuit currentFault loop impedance with short-circuit current - without triggering the residual current circuit breakerNetwork impedance with short-circuit currentNetwork voltagePhase detection. 1 test device with mobile measuring tip 4 batteries (AAA) 1 case 1 short operating instructions 1 CD-ROM with operating instructions in the available languages 1 factory calibration certificate
