Description

M507A | METRALINE Z / CHECK, VDE0100 loop resistance tester

The test device is used to measure fault loop impedances and network impedances.
The measuring range from 0 to 200 Ω (0.27 Ω to 200 Ω according to VDE 0413 / EN 61557) enables a short-circuit current calculation from 0 to 23 kA.

The METRALINE Z-CHECK enables the following measurements:

  • Error loop impedance with short circuit current
  • Error loop impedance with short-circuit current - without triggering the RCD
  • Line impedance with short-circuit current
  • Mains voltage
  • Phase detection

Scope of Delivery:

  • 1 test device with a mobile measuring tip, 4 batteries (AAA), 1 bag, 1 brief operating instructions, 1 CD-ROM with operating instructions in the available languages, 1 factory calibration certificate
