Feature:1. 1. AC Voltage Detection: AC voltage range of 12~300V. Detect the AC voltage and distinguish the neutral-live wire according to the voltage.2. 2. Sound and Light Dual Alarm: When measuring voltage, display screen and buzzer double prompt.3. 3. Flashlight: LED light function provides light in dark environments.4. 4. Wire Conduction Function: If the wire is connected normally , the \"--C\" buzzer will be displayed. If the wire is open, the electroprobe will not respond.5. 5. Auto Power Off: After about 5 minutes without any operation and no signal detection, the voltage detector will be automatically shut down to extend the battery life.6. 6. Inductive Mode Measuring: When the probe of the test pen is placed close to the AC voltage source, the buzzer sounds. With this function, you can distinguish between zero and live wires, or find the break point of the wire.Specification:The voltage tester is safe, insulated and simple. It supports AC voltage detection, intelligent sound and light alarm, breakpoint detection, intelligent identification of zero and live wire.Features:1.

When testing voltages above 30V, be extra careful, because such a voltage will pose a risk of electric shock.2. Due to manual measurement, the size may be slightly different. Thank you for your understanding.3. Due to different light conditions and different monitors, item color displayed in photos may be showing slightly different from real object.Specifications:Brand: HABOTESTModel: HT89Color: BlackShell Material: ABSDisplay: LCDOperating Voltage: AC Voltage: 12~300V, 50/60 HzMeasurement Error: ±（5% + 3）Operating Temperature: 0~40°CStorage Temperature: -10~50°CHumidity: ≤95%Altitude: ≤2000mSafety Compliance: CAT.II 300VBattery: 1 x 1.5V AAA ( Not Included )Item Size: 14.7*2.6*2.3cm / 5.79*1.02*0.91in Net Weight: 40g / 1.41ozPacking Size: 16*4*2.5cm / 6.30*1.57*0.98inPacking Weight: 55g / 1.94ozPackage List:1 * Voltage Tester1 * Manual ( English )Package List:1 * Voltage Tester1 * Manual ( English )
