Safely. Dual-color LED indicators and a transparent design make circuit testing accurate and intuitive for professionals and DIYers alike. Smart Zero & Live Wire Identification Eliminate guesswork when testing outlets and wiring. The intelligent dual-color LED system provides immediate visual feedback. When touching the tail cap and contacting a live wire, both red and green LEDs illuminate brightly. For a neutral (zero) line, only the green LED lights up. This clear distinction ensures safe and accurate diagnostics. Wide Application: Safely tests voltages from 24V to 250V, making it perfectly compatible with standard US outlets (110V/120V) as well as EU/UK systems (220V/240V). Dual-Color LED Instant Response Global Compatibility Built-in Self-Test & Transparent View Never second-guess your tool's status. Before any operation, simply hold the tip and touch the top metal cap simultaneously to perform a self-check; a bright green light confirms the battery and circuit are functioning correctly. The clear PVC housing allows for a complete view of the internal precision circuitry, giving you confidence in its build quality. The fully insulated, thickened PVC housing protects you from electrical shock, ensuring maximum safety during every test. Safety Self-Check Visible Circuitry Fully Insulated PVC Durable Alloy Steel Screwdriver Bit Designed for utility beyond testing. The tip is crafted from high-hardness alloy steel (86-93HRA), making it a reliable slotted screwdriver for standard terminal screws. Combined with a robust, impact-resistant handle, it’s built to withstand the demands of daily work environments. Slotted Tip High Hardness Alloy Dual-Purpose Tool Technical Specifications Details and parameters of the voltage tester pen. Product Type LED Voltage Tester Pen Indicators Dual-color LED (Red & Green) Voltage Sensitivity 24-250V Tip Material High Hardness Alloy Steel (Slotted) Housing Material Transparent PVC Overall Length 15.5 cm / 6.1 in Battery 3 x LR41 Button Cells (Included) Primary Functions Zero/Live Wire Check, Self-test, Screwdriver Frequently Asked Questions How do I perform the self-check before use? To ensure the tester is working and has battery power, hold the metal pen tip with one hand and simultaneously touch the metal tail cap with your other hand. If the green LED lights up, the pen is functional and ready for use. How do I know if a wire is live? While touching the top metal cap with your finger, place the tip against the wire or insert it into the outlet slot. If both red and green lights illuminate brightly, it indicates a live wire. If only the green light turns on, it is a neutral line. Can I use this as a regular screwdriver? Yes, the tip is made of high-hardness alloy steel and is designed as a slotted screwdriver. It is suitable for standard light-duty screwing tasks, such as tightening terminal screws on outlets or switches. Are batteries included and how do I replace them? Yes, batteries are included and pre-installed. To replace them, simply unscrew the top metal cap, remove the old button cells, and insert the new ones matching the polarity. Safety Warning: Always perform the self-test before use. Do not use the tester if it appears damaged or operates abnormally. Keep out of reach of children.
