Feature:1. Intelligent Voltage Tester: detect AC voltage by contacting the power socket or getting near the live wire with non-contact tip.2. High and Low Sensitivity Adjustment: dual sensitivity AC voltage range of 12V~1000V \u0026 48V~1000V with switching S button.3. Zero and Live Wire Distinguished: you can recognise the zero and live wire according to the signal intensity detected, the one with strong signal is live wire.4. Auxiliary Illumination: with flashlight function for lighting up the working area at night.5. Auto Power-off: automatically turn off when no operation and no detection of AC voltage after 5 minutes.6. Low Power Consumption: powered by 2pcs 1.5V AAA batteries(NOT included), and it has low battery indicator when the battery voltage is less than 2.5V.Specification:Features:Intelligent Voltage Tester: detect AC voltage by contacting the power socket or getting near the live wire with non-contact tip.High and Low Sensitivity Adjustment: dual sensitivity AC voltage range of 12V~1000V & 48V~1000V with switching S button.Zero and Live Wire Distinguished: you can recognise the zero and live wire according to the signal intensity detected, the one with strong signal is live wire.Auxiliary Illumination: with flashlight function for lighting up the working area at night.Auto Power-off: automatically turn off when no operation and no detection of AC voltage after 5 minutes.Low Power Consumption: powered by 2pcs 1.5V AAA batteries(NOT included), and it has low battery indicator when the battery voltage is less than 2.5V.Specifications:Material: ABSAC Voltage Detecting Range: 12~1000V, 50/60HzOperating Temperature: 0~40Storage Temperature: -10~50Humidity: ≤95%Altitude: ≤2000mSafety Compliance: CAT III 1000V, CAT IV 600VPower Supply: 2 * 1.5V AAA battery (NOT included)Item Size: 145 * 27 * 24mm / 5.71 * 1.06 * 0.94inItem Weight: 32g / 1.13ozPackage Weight: 47g / 1.66ozPackage Size: 15.5 * 3.5 * 3cm / 6.10 * 1.38 * 1.18inPacking List:1 * Test Pen1 * Manual (English)Package List:1 * Test Pen1 * Manual (English)
