About High Current Ammeters

Ammeters measure the current within an electrical circuit. They measure current in two metrics

  • Draw
    • the flow of current in a particular circuit
  • Continuity
    • the steadiness of the current and the presence or absence of interruptions

Ammeters are used to detect problems in electrical circuits - unusually high or low levels of current, for example. The former can indicate malfunctioning components for a short circuit, while the latter can be a sign of disruptive interruptions or unusual electrical impedance. It is routine to check sockets or outlets using an ammeter when conducting repairs or changing a fuse.
