GVDA GD104 Socket Tester User Manual

Model: GD104

1. Introduction

The GVDA GD104 Socket Tester is a professional tool designed to quickly detect the correct wiring of sockets, measure phase voltage, leakage voltage, and perform RCD (Residual Current Device) or GFCI (Ground Fault Circuit Interrupter) tests. This manual provides essential information for the safe and effective use of your GD104 Socket Tester.

2. Safety Instructions

Warning:

  • Please read this manual carefully before use and strictly follow all safety instructions.
  • Check the tester carefully before using it. If there is any damage, stop using it immediately and send it for repair.
  • Always insert the tester into a known correct socket for testing to ensure its functionality before use.
  • The RCD/GFCI test must be performed under proper wiring conditions.
  • When performing an RCD/GFCI test, ensure all equipment on the power line is closed to prevent harm from power failure. Obtain permission before testing in public places.
  • If detecting incorrect socket wiring, consult a professional electrician for maintenance.
  • The test time for RCD/GFCI should not exceed 5 minutes.
  • When using, be careful not to accidentally touch the RCD (or GFCI) button to avoid triggering the leakage protection switch unnecessarily.
