Gossen Metrawatt METRALINE Z-CHECK Loop Resistance Measuring Instrument
The METRALINE Z-CHECk allows measurement of fault loop impedances and line impedances.
The measuring range from 0 through 200 Ω (0,27 Ω through 200 Ω per VDE 0413 / EN 61557) allows short-circuit current calculation from 0 through 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
Features
- 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 means of securing test probes
- Compact and rugged - for service calls and laboratory use
