Description

Feature	Details
Product Name	Gossen Metrawatt METRALINE Z-CHECK — Loop Resistance / Fault-Loop Impedance Tester
Brand	Gossen Metrawatt
Instrument Type	Loop / Earth-fault / Line Impedance / Fault-Loop Impedance Tester (specialised measuring instrument) (gossenmetrawatt.de)
Main Measurements & Functions	- Fault-loop / earth-fault loop impedance with calculation of short-circuit current (0.27 Ω … 200 Ω) (gossenmetrawattusa.com) - Loop/Line impedance testing even without tripping residual-current devices (RCDs / RCCBs) — useful for safe testing under live circuits. (gossenmetrawatt.de) - Line voltage and phase detection (to assess phase/neutral or phase/earth correctly) (gossenmetrawatt.de) - Automatic evaluation against stored protective-device parameters (fuse/trip-characteristic tables) for safety compliance evaluation. (gossenmetrawattusa.com)
Measuring Range / Specs	0.27 Ω … 200 Ω (nominal per EN 61557-3 / VDE 0413 standard) (gossenmetrawattusa.com) Allows short-circuit current calculation up to ~23 kA (useful for system fault-current assessment). (gossenmetrawatt.de)
Display & Interface	Digital back-lit colour OLED display (with brief/detailed representation), built-in measurement-point LED illumination for dark/limited-light environments, compact & rugged handheld housing. (gossenmetrawattusa.com)
Safety & Standards Compliance	Conforms to relevant standards for loop-impedance testers: EN 61557-1 / 61557-3 (safety testing for low-voltage installations up to 1000 V). (gossenmetrawattusa.com) Safety classification for general low-voltage testing (use as per manufacturer instructions) (ManualsLib)
Typical Applications / Use Cases	- Fault-loop / ground-fault / earthing-impedance verification in installations - Electrical safety testing for residential, commercial and industrial wiring - Maintenance checks in buildings, factories, plants, switch-rooms - Verification of compliance with safety/earthing regulations before commissioning or periodic inspection - Pre-inspection before energizing circuits, after maintenance or repair — useful for electricians, safety inspectors, installation teams in Qatar and similar environments
