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. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.

4. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   The measurement of the electric current can be classified depending upon the underlying fundamental physical principles such as, Faraday's Law of Induction; Magnetic field sensors; Faraday effect; Transformer or current clamp meter, (suitable for AC current only). Fluxgate sensor, (suitable for AC or DC current).

5. Electronic test equipment - Wikipedia

   en.wikipedia.org/wiki/Electronic_test_equipment

   A multimeter with a built in clamp facility. Pushing the large button at the bottom opens the lower jaw of the clamp, allowing the clamp to be placed around a conductor (wire). Depending on sensor, some can measure both AC and DC current. RF probe; Signal tracer

   The output of the amplifier is then connected to the inductor under measurement. To monitor and control the current flowing through the inductor, a current clamp meter is clamped around the conducting wire. An oscilloscope connected to the current clamp to measures the current waveform. A probe measures the flux in the air.
