CALVAN AmpHound 2 CV72 Introducing the Amp Hound 2. The Amp Meter for Fused Circuits! CONVENIENT: Attach the adapter to fuse or just touch the probes to the top of the fuse. AUDIBLE: Tone lets you know when you are touching a fuse. No guesswork, no need to stare at the meter. This makes working in under-the-dash fuse boxes much simpler. FUSE TYPES: Works on new fuse types Mini-LP and Micro-Fuse, along with three of the most common automotive fuses types: Mini, Standard, and Maxi with all of the most common ranges. SAFE: No chance of shorting a circuit while the fuse is removed. Real-time readings of current and amps in a fused circuit without removing the fuse. Special Fuse Adapters lock on to fuse to give user hands-free control. Includes all features from original Amp Hound that allows easy component testing and Parasitic Drain location. Takes amperage readings without having to access hard to reach components.
