1. Introduction
The HABOTEST HT106B Socket Tester is a compact and portable device designed for quick and accurate detection of socket wiring status. It features RCD (Residual Current Device) or GFCI (Ground Fault Circuit Interrupter) testing capabilities and voltage measurement with an LCD display. This manual provides essential information for safe and effective use of the device in various settings, including schools, laboratories, and factories.

2. Safety Instructions
⚠ Warning:
- Always read this instruction manual carefully before use and strictly observe all safety rules, cautions, and warnings.
- To avoid possible electric shock or personal injury, always check the tester carefully for any damage before use. If any damage is found, discontinue use immediately and send it for repair.
- Ensure the RCD test is performed only under correct wiring conditions.
- When performing an RCD test, ensure all equipment on the power line is closed to prevent power failure or harm. Obtain permission if testing in public places.
3. Setup
The HT106B Socket Tester is designed for immediate use. Simply plug the device into a standard three-hole power outlet to begin testing.

4. Operating Instructions
4.1. Voltage Test
Insert the tester into a standard three-hole power outlet. The socket voltage value will be displayed on the tester's LCD screen in Volts (V).
- The test duration should not exceed 5 minutes.
- Exercise caution to avoid touching the RCD button during voltage testing to prevent accidental tripping of the leakage protection switch.

4.2. RCD (or GFCI) Test
Insert the tester into a correctly wired three-hole power socket. Press the RCD/GFCI test button for less than 3 seconds. A properly functioning RCD/GFCI should trip (turn off the power) at this time. If the RCD/GFCI does not trip, it indicates a failure and requires professional electrician maintenance.
- The test duration should not exceed 5 minutes.
- RCD and GFCI functions cannot be used simultaneously.
4.3. Wiring Status Detection
The HT106B Socket Tester uses a series of indicator lights to quickly identify the wiring status of the socket. Refer to the functional control table and indicator results below to interpret the findings.

| Indicator Pattern | Wiring Status |
|---|---|
| Two red lights (top row) | CORRECT: Lines are connected normally. |
| Red light in the middle (top row) | OPEN GROUND: The ground line is missing. |
| Red light on the left (top row) | OPEN NEUTRAL: The neutral wire is missing. |
| No red light (top row) | OPEN LIVE: Lack of "fire line" (live wire). |
| Two red lights on the right (top row) | LIVE/GRD REVERSE: Live and ground wires are misconnected. |
| Red lights on the left and right (top row) | LIVE/NEU REVERSE: Wrong connection of live and neutral wires. |
| All three red lights (top row) | LIVE/GRD REVERSE, MISSING GRD: Faulty phase connection and missing ground. |
Note: This tester cannot distinguish between neutral line and ground wire reverse.
5. Maintenance
Cleaning
Clean the tester with a soft, damp cloth. Do not use abrasive cleaners or other chemicals, as they may damage the device. Ensure the tester is completely dry before its next use.
6. Troubleshooting
- RCD/GFCI does not trip during test: This indicates that the RCD/GFCI has failed. Immediately contact a professional electrician for inspection and repair.
- Wiring fault detected (e.g., Open Ground, Live/GRD Reverse): If the tester indicates a wrong connection, consult a professional electrician to repair the wiring. Do not attempt to fix faulty wiring yourself unless you are qualified.
