Line breakpoint search,Search along in the "EF" NCV gear. If the signal is strong, the road is smooth and good. If the signal is weak, is disconnected Flashlight VA Color display,The lighting assists nighttime measurement work, eliminates the risk of , 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 be. You can distinguish between neutral and live wires DC voltage measurement,Switch to DC voltage, 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 show the corresponding voltage value Product model:VD808 Product Name: Socket Circuit Analyzer Alarm mode:buzzer alarm Rated current:1An=30mA Use battery:2 x 1.5V AA batteries (Not included batteries) Socket rated voltage:Un=220V-250AC AC voltage:12-300V 50Hz-60Hz Accuracy: (4%+10) (The product printed words depending on the batch, but this does not affect use) Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on Voltage:AC100-240V Color: As Shown Material: ABS Package Contents: 1 * Circuit Breaker Finders Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
