GFUVE All Mini Medium Large Jaw Full Current Clamp Combo

In this complete unboxing and practical test video, we fully display all three categories of split-core probes inside the all-range combo: φ13 slim mini clamps, φ50/110 medium standard clamps and φ120/150 large bus clamps. We conduct real clamping tests on PCB thin traces, factory cabinet cables and substation copper busbars respectively, and compare multi-channel synchronous test data of uniformly calibrated full set vs scattered separate clamps from different suppliers. The video demonstrates the operation of three interchange signal cables matching oscilloscopes, handheld multimeters and data loggers, and explains the dual magnetic core selection logic for low-frequency grid and high-frequency power electronics testing. We also introduce the classified shockproof storage bag structure, full UL/CE/CNAS certification system and three-year global warranty policy. At the end of the video, we elaborate all customizable services including jaw quantity ratio adjustment, signal ratio modification, neutral OEM packaging and project calibration document provision for overseas distributors, EPC contractors and university labs. This all-in-one combo eliminates repeated multi-supplier procurement and inconsistent data troubles, becoming the most cost-effective complete testing solution for cross-scene electrical measurement.
