1. Introduction
This product is primarily designed for the polarity detection of three-hole power socket wiring and the functional testing of leakage switches. It offers a quick and accurate method to assess the wiring condition of a socket, helping to identify issues that could lead to electric shocks, electrical fires, or abnormal equipment operation. The GVDA GD101B is widely utilized in fire protection, safety supervision, home improvement, laboratory settings, factories, and for general home line inspection and maintenance.
Safety Warnings
- Please read this instruction manual carefully before use and strictly adhere to all safety rules, cautions, attentions, and warnings provided. This is crucial to prevent potential electric shock or personal injury.
- Before each use, carefully inspect the tester for any damage. If the device appears damaged, discontinue use immediately and send it for repair.
- To verify the tester's functionality, plug it into a known correctly wired socket and confirm that its test functions operate as expected before proceeding with other tests.
- When performing switch detection, ensure the wiring is correct for normal operation.
- When testing the leakage switch (RCD), always turn off all electrical appliances connected to the power line to prevent any harm from power failure. If testing in public areas, ensure proper authorization.
- If the socket wiring error is detected, consult a professional electrician for repair.
2. Setup
2.1. Battery Installation
Before using the device, open the battery cover and insert two AAA batteries. Ensure correct polarity.
3. Operating Instructions
3.1. Power On/Off
Long press the power button for approximately 2 seconds to turn the device on. The display will illuminate.
3.2. Basic Socket Testing
Plug the GVDA GD101B Socket Tester into the three-hole socket you wish to test. The device will automatically display the current socket line status and voltage readings.
3.3. Test Status Analysis
The tester's display provides clear indications of various wiring conditions:
| Display Indication | Meaning |
|---|---|
| The wiring is correct | The socket is correctly wired. |
| Missing zero line | The neutral wire is not connected or is faulty. The corresponding icon will flash an alarm. |
| Missing ground | The ground wire is not connected or is faulty. The corresponding icon will flash an alarm. |
| Fire ground reverse | The live (fire) wire and ground wire are reversed. The corresponding icon will flash an alarm. |
| Fire zero reverse | The live (fire) wire and neutral (zero) wire are reversed. The corresponding icon will flash an alarm. |
| Mismatch and lack of land | Indicates a combination of wiring errors, including a missing ground connection. The corresponding icon will flash an alarm. |
3.4. RCD Test
To perform an RCD (Residual Current Device) test, insert the tester into the three-hole socket. Ensure the display indicates "The wiring is correct". Then, press the RCD button for less than 3 seconds. A functional leakage switch should trip. If the switch does not trip, it indicates a failure or absence of the leakage switch, and professional electrician maintenance is required.
3.5. Socket Polarity Detection
The GVDA GD101B provides clear readings for zero-live voltage, allowing for quick detection of socket polarity. This helps ensure that the live and neutral wires are correctly positioned, which is vital for electrical safety.
3.6. Color Display Features
The device features a high-definition color display, ensuring clear visibility of screen values even in dimly lit environments.
4. Maintenance
4.1. Battery Replacement
To prevent electric shock or injury due to incorrect readings, replace the batteries immediately when the battery undervoltage symbol appears on the meter. Always turn off the power and confirm that the socket tester has been removed from the measurement circuit before opening the battery cover to replace the batteries.
5. Troubleshooting
5.1. Special Attention Points
- The normal voltage range for the zero-fire line should be within plus or minus 10% of the local standard voltage. If the reading is too high or too low, it may indicate that the circuit load is excessive, or the power supply is unstable (too low/too high).
- The normal voltage of the zero-earth wire should be less than 2V. A higher reading might suggest current leakage, an imbalance in the three-phase sequence, or signal interference within the circuit.
