Glossary “analog-to-digital converter” Definition:
Electrical device used to convert analog signals to a digital code that represents the amplitude of the original signal.
a
amplifier
Glossary “amplifier” Definition:
A device used to increase the strength of the applied signal.
amplitude
Glossary “amplitude” Definition:
1). The difference between the highest and lowest voltage displayed. 2). The magnitude of an electrical signal above or below some reference, usually measured in voltage above or below “0”
AMV
Glossary “AMV” Definition:
Air Management Valve
anaerobic chemical
Glossary “anaerobic chemical” Definition:
Hardens only in the absense of air, hardens under pressure (Super Glue).
anaerobic sealants
Glossary “anaerobic sealants” Definition:
Chemical sealant placed on a gasket to aid in sealing and to position the gasket during installation.
ampere (A)
Glossary “ampere (A)” Definition:
A unit of measure for current.
ampere turns
Glossary “ampere turns” Definition:
The unit of measurement for electrical magnetic field strength
amplification
Glossary “amplification” Definition:
Increase in signal amplitude from one point to another.
amp/hour
Glossary “amp/hour” Definition:
Amperes per hour; a standard measure for a rate of current flow.
ampacity
Glossary “ampacity” Definition:
The current-carrying capacity of conductors or equipment, expressed in amperes.
amperage
Glossary “amperage” Definition:
The amount of current, expressed in amperes.
amperage capacity
Glossary “amperage capacity” Definition:
An indication of the length of time a battery can produce an amperage, or the amount of amperage that a battery can produce before being discharged.
Ampere
Glossary “Ampere” Definition:
Andre Marie Ampere (1775-1836). Unit of measurement that is used to determine the current flow in a completed circuit was named after him.
American Welding Society (AWS)
Glossary “American Welding Society (AWS)” Definition:
Organization that sets standards for all types of welding.
American wire gauge (AWG)
Glossary “American wire gauge (AWG)” Definition:
A standard for the measurement of the size of wire. The higher the gauge number, the smaller the wire.
AMM
Glossary “AMM” Definition:
Air Mass Meter
ammeter
Glossary “ammeter” Definition:
An instrument used to determine the amount of amperage (current draw) in a circuit by connecting the ammeter in series with the circuit and measuring the total number of electrons flowing in the circuit. May use an inductive probe that measures the strength of the magnetic field that is created by the current flowing through the wire to determine current flow in a circuit.
ammeter shunt
Glossary “ammeter shunt” Definition:
A low-resistance conductor used to increase the range of an ammeter. It is shunted (placed in parallel) across the ammeter movement and carries the majority of the current.
amp
Glossary “amp” Definition:
Term for Ampere.
