Meter? I hardly know her.
A test instrument that measures current in a circuit by measuring the strength of the magnetic field around a single conductor.
Clamp-on ammeter
Voltage in a circuit that has current that flows in one direction only.
DC Voltage
An electromechanical device that indicates readings by the mechanical motion of a pointer.
Analog Display
The process of removing the source of electrical power and installing a lock that prevents the power from being turned ON.
Lockout
A regulation or minimum requirement.
Code
Test instrument that indicates the presence of voltage when the test tip touches, or is near, an energized hot conductor or energized metal part.
The number of electrons passing a given point in 1 sec.
Ampere
A test instrument that measures voltage.
Voltmeter
An area that has limited openings for entry and/or unfavorable natural ventilation that could cause a dangerous air contamination condition.
Confined Space
A current-carrying conductor that carries current from the load back to the power source and is intentionally grounded.
Grounded conductor / Neutral Conductor
A portable test instrument that is capable of measuring two or more electrical properties.
The opposition to the flow of electrons in a circuit.
Resistance
A test that identifies specific pairs of wires within a system.
Tone or probe test or ring out
An explosion that occurs when the air surrounding electrical equipment becomes ionized and conductive.
Arc Blast
An accepted reference or practice.
Standard
A test instrument that tests for a complete path for current to flow.
Continuity tester
The amount of electrons flowing through a conductor, component, or circuit.
Current (I)
A measurement taken when a test instrument is briefly connected to a circuit or to a component and then removed.
Electrical Measurement
An extremely high-temperature discharge produced by an electrical fault in the air.
Arc Flash
A current-carrying conductor that is connected to loads through fuses, circuit breakers, and switches.
Ungrounded Conductor / Hot Conductor
A high-resistance ohmmeter used to measure insulation deterioration on various wires by measuring high resistance values during high voltage test conditions.
Megohmmeter
root-mean-square (effective) value (Vrms)
The value of an AC sine wave that produces the same amount of heat in a pure resistive circuit as DC of the same value.
A meter that can measure two or more electrical properties and displays the measured properties along calibrated scales using a needle.
Analog Multimeter
A personal protective device that provides electricians protection from electrical shock when working on energized electrical circuits.
Rubber insulating matting / probably lots of other things.
A conductor that does not normally carry current, except during a fault (short circuit).
Grounding conductor / Ground wire
