NON-CONTACT VOLTAGE TEST PEN - This non-contact voltage test pen is 12-250V, used for home inspection of general electronics, electronic leaks and polylines. HIGH EFFICIENCY - As soon as the voltage test pen detects voltage, the test pen LED will light up and display the voltage with a digital display. FAST AND ACCURATE TEST - This electrical test pen checks the wires and tells you what is Which live wire and which ground wire allows you to check or test safely, quickly and accurately. EASY TO USE - You can use this non-contact voltage detector to sense voltage and control the safety of power into circuit breakers, light fixtures, switches, outlets, wires and anywhere you need it. SAFE CONVENIENT - This volt pen tester detects voltage without contact. So you don't have to worry about the possibility of electric shock, it is very safe. Type: With Light / Without Light Material: plastic, metal Test range: 12 ~ 250V AC DC Feature: It checks general electrical products, electronic leaks and broken lines. It checks the wire and tells you what is hot (fire) and cold (earth) . Allows you to check or test safely, quickly and accurately. Lightweight and easy to carry. Easy to use. Durable in use. Perfect for home use and convenient when checking holiday lights. Voltage detection: 1. The last digits are the voltage value. 2. It will indicate the lower value otherwise it will reach 70% of the display value of the high value. 3. Please touch the negative pole when testing DC voltage. 4. The inductor can be used when you test the element with a voltage lower than 12V 5. It should be connected to ground or zero when testing the element with induction. Sensor detection: When detecting a side-by-side line, please increase the space between the lines or hold the detected element by hand. Break detection: Move along the phase line, when nothing is displayed in the display window, this is the point of stop. Package Include: 1 x Electric Test Pen (Batteries Not Included) Note: It does not include other things, the color is based on the first picture and others Pictures only show effect Due to the differences between different monitors, the picture may not reflect the actual color of the item.
