Featuring an open-jaw design, this powerful electrical tester enables non-invasive AC current measurements up to 200 Amps directly over conductors without breaking active circuits. Seamlessly integrated with high-performance True RMS technology, it accurately interprets distorted waveforms on complex commercial equipment, allowing for swift and reliable fault-finding in tight, high-density distribution environments.\u003c\/p\u003e\n\u003cp\u003eBuilt for survival on demanding jobsites, the GFM1000-15 features a rubber-reinforced housing that is field-tested to withstand accidental drops from up to 6 feet and is protected by an IP54 dust and splash resistance rating. This all-in-one instrument records AC\/DC voltages up to 1000 Volts and integrates specialized features like low-input impedance (LoZ V) to automatically eliminate phantom ghost voltages. Complete with a built-in non-contact voltage (NCV) detector, an integrated LED panel flashlight, and an uncompromised CAT IV 600V \/ CAT III 1000V certified safety rating, it delivers ultimate field confidence and reliable one-handed usability.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid Non-Invasive Diagnostics:\u003c\/strong\u003e Open-fork jaw design captures fast AC current measurements without lead connections or circuit interruptions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced True RMS Accuracy:\u003c\/strong\u003e Engineered to provide highly reliable, precise electrical readings on non-sinusoidal waveforms and active variable loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoZ ghost Voltage Elimination:\u003c\/strong\u003e Low input impedance mode filters out misleading ghost voltage readings across adjacent live wiring runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRugged Heavy-Duty Architecture:\u003c\/strong\u003e Rubber-molded ergonomic grip resists jobsite abrasion, drop-tested up to 6 feet with an IP54 weatherproofing rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Source Power Versatility:\u003c\/strong\u003e Operates universally on standard AA batteries or a professional 3.7V Lithium-Ion rechargeable pack for diminished downtime.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Safety NCV Sensor:\u003c\/strong\u003e Built-in non-contact voltage tester provides fast, audio-visual proximity checks before managing exposed wires.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Visibility Inverted Screen:\u003c\/strong\u003e Crystal-clear, high-contrast inverted LCD ensures immediate visibility inside unlit industrial enclosures or basements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Safety Compliance:\u003c\/strong\u003e Certified to elite CAT IV 600V and CAT III 1000V safety classes with integrated protective power cuts when battery doors open.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Bosch PRO GFM1000-15 True RMS Fork Meter\u003c\/li\u003e\n\u003cli\u003e(1) Set of High-Quality Flexible Silicone Test Leads\u003c\/li\u003e\n\u003cli\u003e(2) Standard AA Batteries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 61.4286%;
