This pen-type digital meter is a small 6000-bit true RMS automatic scanning digital instrument. According to the difference between voltage/resistance/capacitance/diode. Features: Intelligent Zero-FireWire Recognition: Select Live zero-firewire differentiation function, insert the pen needle into the hole for recognition, no need for traditional contact measurement. NCV Non-Contact Induction: When AC voltage is detected in the vicinity, the LED indicator lights up red and an alarm beep sounds. Line Break Detection: In NCV non-contact voltage detection mode, single stranded wires are energized to detect the location of breaks along the line. VA Color Screen Lighting: Can provide lighting in dark environments to cope with complex working environments. Detachable Positive Nib: Silver plated, oxidation-resistant, not easy to break and wear, use pliers to hold the stainless steel nib to rotate out, with cap conservation. Intelligent power-saving automatic shutdown: When the intelligent pen does not operate within 15 minutes and no voltage signal is detected, it will automatically shut down.
