AD-5571 Non-Contact Voltage Tester

AD-5571 Non-Contact Voltage Tester

Detailed Description & Specifications

The AD-5571 is a sophisticated, pen-style non-contact voltage tester (NCVT) designed for electricians and technicians to safely and efficiently detect the presence of AC voltage. It combines clear visual and audible alarms with unique features like a dual-range sensitivity mode and a built-in white LED work light, making it an essential tool for a wide range of electrical testing applications, from low-voltage systems to standard mains voltage.

Key Features & Capabilities

• Dual-Range Voltage Detection: Select between two sensitivity modes for versatile application.

  • Low Voltage Response Mode (24-1000V AC): Ideal for detecting weaker electromagnetic fields. The Status Indicator blinks green. Perfect for arc welding circuits, audio systems, and checking insulated cables.

  • High Voltage Response Mode (90-1000V AC): Standard mode for general-purpose electrical work, reducing the chance of false positives. The Status Indicator blinks red.

• Clear Multi-Sensory Alarm System: Upon detecting a live AC voltage, a bright red LED on the tip of the pen flashes, and an integrated buzzer sounds simultaneously, ensuring clear indication in both noisy and visually demanding environments.

• Integrated White LED Work Light: Features a dedicated white LED at the tip, functioning as a penlight to illuminate dark electrical panels, junction boxes, and work areas, even when the voltage detection function is powered off.

• Enhanced Safety & Usability:

  • Auto Power-Off: Conserves battery life by automatically shutting down approximately 5 minutes after the last use, with a warning beep.

  • Low Battery Warning: The Status Indicator flashes yellow-green three times and the buzzer sounds before the device turns off, providing ample warning to replace batteries.

  • High Safety Rating: Certified for Overvoltage Category CAT IV, suitable for use on the source of the low-voltage installation (e.g., overhead lines, service cables).

• Compact & Portable Design: Pen-style form factor with a lightweight build (approx. 50g) and a pocket clip for easy portability. Includes a hole for attaching a commercially available wrist strap.
