Current clamps are also referred to as clamp-on current probes or Amp clamps in America. They enable you to measure currents without breaking the electrical circuit. Current clamps feature opening and closing jaws that can be placed around a wire (conductor) where a magnetic loop is formed.
Current clamps can either be connected to an Oscilloscope with a BNC Test lead or Multimeter through a Banana Plug Patch Lead. The specification of Current Clamps varies on; Amp Ratings, AC/DC functionality, Jaw size and display system. It’s important to match instrument specification with intended use to ensure accurate and reliable electrical testing.
Here we look to explore and explain why the Current Clamp is an important and versatile instrument that every Automotive Technician should have in there tool box.
