M507A METRALINE Z-CHECK, loop resistance measuring instrument

The test instrument is used to measure fault loop impedances and line impedances. The measuring range of 0 to 200 Ohms (0.27 Ohms to 200 Ohms according to VDE 0413/EN 61557) allows short-circuit current calculation from 0 to 23 kA.

The METRALINE Z-CHECK enables you to carry out the following measurements:

- Fault loop impedance with short-circuit current - Fault loop impedance with short-circuit current - without tripping the F1 switch - Line impedance with short-circuit current - Line voltage - Phase detection

Features - Table of common protective devices can be displayed if required - Digital display, backlit, colour OLED display, - Switching between a shorter and a more detailed presentation - LED for measurement point illumination - Patented means of securing test probes - Compact and robust - for service calls under harsh conditions and laboratory use

Included with delivery: Test instrument with mobile test probe, four batteries (AAA), carrying case, quick start guide, CD-ROM with operating instructions, works calibration certificate
