AND AD-5571 Non-contact Voltage Tester

AND AD-5571 Non-contact Voltage Tester

Description

• The AND AD‑5571 is a non‑contact voltage tester that detects AC voltage without touching bare conductors.

• When an AC voltage signal is detected, the red LED at the tip of the pen flashes and a buzzer sounds, providing clear visual and audible alerts.

• Features selectable detection ranges (24–1000 V or 90–1000 V) with easy sensitivity switching at the touch of a button.

• Low Voltage Response Mode (24–1000 V) – status indicator panel blinks green. Ideal for arc welding, audio systems, insulated cables, and detection of weak electromagnetic AC signals.

• High Voltage Response Mode (90–1000 V) – status indicator panel blinks red. Suitable for inspection of distribution boxes, switchboards, electrical fixtures, equipment, lead‑in lines, and 3‑phase AC power supplies.

• Includes a low battery display – when battery voltage is low, the status indicator panel flashes yellow‑green 3 times, the buzzer sounds, and the device turns off automatically.

• Auto power off – approximately 5 minutes after last use, the buzzer sounds and the device shuts down to conserve battery.

• Equipped with a white LED light for illumination in dark work areas.

• Features a strap attachment point for use with a commercially available wrist strap.

• Compliant with overvoltage category CAT IV for safe use on low‑voltage installations.
