Handheld Digital Multimeter Pen 4000 Counts Non-Contact Auto AC/DC Voltage Ohm Diode Tester Product features.1. A variety of functional uses, power on that is measured, automatic identification of gear2. NCV non-contact induction contactless power measurement: built-in sensor, red light when the detection of nearby AC voltage indicator flashes, the closer to the power supply alarm more urgent3.Live zero fire line line wiring detection: LIVE mode insert the meter head into the hole to determine the zero line fire line fire line display H accompanied by a beeping sound, zero line no response4. Line breakpoint detection breakpoint judgment: in NCV non-contact voltage detection mode, single-stranded line with power along the line to investigate the location of the breakpoint5. High bright flashlight for you to illuminate the front: no longer afraid of the dark environment at night can assist in lighting the use of invisible measurement location, to eliminate the risk of electric shockProduct parameters.Product Model: A3005AC voltage: 0.8V-600VDC voltage: 0.8V-600VResistance: 0.1~40MNCV inductionSpportLive zero fire lineSpportBuzzerSpportBacklight screenSpportAuto Power OffSpportData Hold: SpportLow battery alert: SpportMaterial: ABSMaximum count: 4000Battery: AAA*2 (shipped without battery)Package and list.
