AC Voltage Detector 012 Multifunctional Socket Circuit AC/ Voltage Tester Intelligent Power Polarity Detector Leakage Test Tools Features: Non-Contact Voltage: to the "EF" position, place the probe tip of the test pen close to the AC voltage source, and ensure reliable contact between the finger and the contact point. The closer it is to the power source, the more urgent the alarm will sound. Flashlight with Screen Backlight: The lamp assists in night measurement work, eliminating the risk of electric , illuminating the dark environment ahead and allowing you to see the screen values clearly, with clear backlight. AC Voltage Measurement: The pen tip is tightly attached to the AC voltage conductor, while the finger is in close contact with the contact point, and the corresponding AC voltage value is displayed on the display screen. Voltage Measurement: to the voltage , hold down the pen tip of the negative electrode of the 1.5V or 9V battery with one hand to make contact with the positive electrode of the battery, and make close contact with the contact point with the other hand. The corresponding voltage value will be displayed on the display screen. Wire Continuity Detection: to the P-C position, hold one end of the uncharged wire with one hand, make contact between the probe tip and the other end of the wire, and ensure reliable contact between the hand and the contact point.
