Description Non-contact AC Voltage Detector The UT12D from Uni-T is a simple and very handy electrical tool to detect the presence of any AC voltage above 24V. The user is fully protected from the voltage because the UT12D Voltage Detector doesn’t need direct contact with the electrical conductor or wire – it detects the voltage through the wire’s insulator. Electrical Specifications: Voltage Sensitivity: 24 ~ 1000VAC Bandwidth: 50/60Hz Safety level: CAT IV Voltage Indicators: Audio beep and flashing light Battery Indication: LED will not flash if the battery is less than 2V. Beep sounds may be weaker Silent Indicators: LED flashing only, saving battery Built-in flashlight Auto Power Off: Yes (3 minutes) Low-voltage Mode (<90V) – Green display: audio systems, arc welding machines, underground mining illumination, cables with thick insulation layer, other weak electromagnetic AC signals High-voltage Mode – Red display: urban electrical supply and three-phase systems Package includes: UT12D Voltage Detector, 2 x AAA batteries, Printed User Manual
