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 ...
No automatic protection. A smaller version similar in size to small portable test meters. (Basic ranges to 1 A, DC only and 1000 V, both extendable with external multiplier and shunts [23]). 10,000 ohms/volt DC, 1000 ohms/volt AC. Clamp meter: Principally for higher currents (Ranges 300 A, 600 A, 1200 A, 150 V, 300 V & 600 V all AC only).
Clamp meters clamp around a conductor carrying a current to measure without the need to connect the meter in series with the circuit, or make metallic contact at all. Those for AC measurement use the transformer principle; clamp-on meters to measure small current or direct current require more exotic sensors, such as; hall effect based systems ...
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).
Ammeter, e.g. Galvanometer or Milliammeter (Measures current) Multimeter e.g., VOM (Volt-Ohm-Milliammeter) or DMM (Digital Multimeter) (Measures all of the above) LCR meter - inductance (L), capacitance (C) and resistance (R) meter (measure LCR values) The following are used for stimulus of the circuit under test: Power supplies; Signal generator
A moving coil meter indicates the average (mean) of a varying current through it, [b] which is zero for AC. For this reason, moving-coil meters are only usable directly for DC, not AC. This type of meter movement is extremely common for both ammeters and other meters derived from them, such as voltmeters and ohmmeters.
