Line breakpoint search,Search along the line in the "EF" NCV gear. If the signal is strong, the road is smooth and good. If the signal is weak, the line is disconnected Flashlight VA Color display,The lighting assists nighttime measurement work, eliminates the risk of electric shock, and illuminates the dark environment ahead so that you can see the screen values clearly, even in backlight Non-contact sensing NCV voltage detection,Switch to "EF", bring the probe tip close to the AC voltage source, and make sure your finger is in reliable contact with the contact point. The closer you are to the power source, the more rapid the alarm will be. You can distinguish between neutral and live wires DC voltage measurement,Switch to DC voltage, press the negative pole of a 1.5V or 9V battery with one hand, touch the pen tip to the positive pole of the battery, and touch the contact point with one hand, the display will show the corresponding voltage value Product model:VD808 Product Name: Socket Circuit Analyzer Alarm mode:buzzer alarm Rated current:1An=30mA Use battery:2x1.5V AA batteries Socket rated voltage:Un=220V-250AC AC voltage:12-300V 50Hz-60Hz Accuracy: ±(4%+10) (The product printed words may vary depending on the batch, but this does not affect use) Voltage: AC110V/AC100-240V Plug Type:US Plug,it applies to Canada, India,Mexico, Thailand, the United States, the Philippines,Taiwan and so on.
