The Ermenrich Zing ST30 Socket Tester is designed to test whether all of the sockets are properly wired and to check the voltage. The tester must be plugged directly into a socket and the LED’s flashing will indicate various electrical faults: no ground/no neutral live/neutral reverse or live/ground reverse. In addition the specific color code that appears on the tester screen signals the correct wiring condition. The function of each code is written on the device.

Key features:

  • 230V AC
  • Detects no ground/no neutral
  • Flashes when live/neutral reverse or live/ground reverse
  • A special light code to indicate correct wiring
