Introduction
The DELIXI ELECTRIC Test Pencil is a versatile tool designed for electricians and DIY enthusiasts to safely detect voltage, identify live and neutral lines, and test circuit continuity. It features non-contact induction for enhanced safety and includes a flat or cross-head screwdriver function. This manual provides essential information for the safe and effective use of your test pencil.
Product Features
- Eye-catching high-brightness LED indicators (green/red) for clear detection.
- Intelligent identification of live (fire) and neutral (zero) lines.
- High-torque anti-slip handle for comfortable and secure grip.
- Inductive detection of circuit breaking points and non-contact voltage measurement.
- Line on-off detection for rapid fault identification.
- DC voltage detection and battery level discrimination.
- Strong magnetic screwdriver head (flat or cross-head).
- Intelligent motherboard chip for enhanced security and durability.
Setup
- Battery Installation:
The test pencil requires 3 AG3 button batteries. To install, unscrew the touch level pen cover at the top of the handle. Insert the batteries according to the polarity markings, then securely reattach the cover.

- Initial Self-Test:
Before each use, perform a self-test. Place your hand on the touch electrode (the metal cap at the top of the handle). If the green light on the test pencil illuminates, it indicates that the device is functioning correctly and ready for use.

Operating Instructions
- Voltage Detection (Non-Contact Induction):
Hold the test pencil by its insulated handle. Bring the tip of the test pencil close to the wire or electrical component you wish to test. If voltage is present, the LED indicators will light up (green for neutral/zero line, red for live/fire line, or traffic lights simultaneously for live line). For inductive contact, ensure your hand is on the touch pole/electrode at the top of the handle.

- Live (Fire) Line Identification:
When the test pencil detects a live wire, the red LED indicators will light up, often accompanied by other lights (traffic lights light up simultaneously).

- Neutral (Zero) Line Recognition:
When the test pencil detects a neutral line, the green LED light will remain constantly on.Image: Illustration of Zero Line Recognition, where the green light is always on.
- Circuit Breaking Point Detection:
Use the non-contact induction feature to trace a wire. The lights will indicate the presence of voltage. If the lights stop illuminating along a wire, it indicates a potential break in the circuit at that point. - Line On-Off Detection:
This feature allows for rapid detection of line faults by checking for continuity or breaks in a circuit. - DC Detection / Battery Level Discrimination:
The test pencil can also be used for DC voltage detection and to discriminate battery levels. Refer to the specific light patterns for DC voltage indication. - Screwdriver Function:
The tip of the test pencil functions as a flat or cross-head screwdriver. The strong magnetic batch head helps in holding screws securely.

Maintenance
- Cleaning: After each use, clean the test pencil to remove any dirt or debris. This helps to maintain its functionality and extend its lifespan. Use a dry, soft cloth. Do not use abrasive cleaners or immerse the device in water.
- Battery Replacement: When the LED indicators become dim or the device fails to perform the self-test, it's time to replace the batteries. Follow the battery installation steps in the Setup section. Ensure to use 3 new AG3 button batteries.
- Storage: Store the test pencil in a dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
- No power/No light during self-test or detection:
- Ensure your hand is firmly on the touch electrode during the self-test.
- Check if the batteries are correctly installed and not depleted. Replace batteries if necessary.
- Verify the test pencil is within the specified voltage range (12-220V).
- Inaccurate readings:
- Ensure the tip of the test pencil is close enough to the conductor.
- Avoid testing in areas with strong electromagnetic interference.
- Clean the tip of the test pencil.
- Screwdriver tip not holding screws:
- The magnetic property might weaken over time or with heavy use. Ensure the screws are made of a magnetic material.

User Tips
- AC/DC Compatibility: The test pencil is designed for detecting both AC and DC voltages within the 12-220V range. For AC circuits, it effectively identifies live (fire) and neutral (zero) lines. For DC, it can help in general voltage presence and battery level discrimination.
- Sunlight Observation: The bright LED indicators are designed to be visible even in sunlight, ensuring clear observation during outdoor or brightly lit work environments.
