2. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally ...

3. Ammeter - Wikipedia

   en.wikipedia.org/wiki/Ammeter

   The moving-iron meter was invented by Austrian engineer Friedrich Drexler in 1884. [5] This type of meter responds to both direct and alternating currents (as opposed to the moving-coil ammeter, which works on direct current only). The iron element consists of a moving vane attached to a pointer, and a fixed vane, surrounded by a coil.

4. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   A clamp meter. Any meter will load the circuit under test to some extent. For example, a multimeter using a moving coil movement with full-scale deflection current of 50 microamps (μA), the highest sensitivity commonly available, must draw at least 50 μA from the circuit under test for the meter to reach the top end of its scale. This may ...

5. Current sensing - Wikipedia

   Transformer or current clamp meter, (suitable for AC current only). Fluxgate sensor , (suitable for AC or DC current). Hall effect sensor (suitable for AC, DC, or pulsating current), a type of current sensor which is based on the Hall Effect phenomenon discovered by Edwin Hall in 1879.
