A micrometer is a precision measuring instrument. The instruments used on the CP course can measure down to .01mm (Metric - one hundreth of a millimeter), or 0.001" (Imperial - one thousandth of an inch).

Micrometer with parts named.

Apprenticeship training in Ireland is now standards based (SBA). In other words, it differs from the old time based system in that a defined and agreed standard must be reached by each trainee at the end of each phase of training before they can move on to the next phase.

There are 7 phases of training for CP Fitters. Phases 2, 4 and 6 are "off the job". Phase 2 is delivered in the DDLETB training centre, Baldoyle. Phases 4 and 6 are delivered in the Institute of Technology in Cork.

Phase 2 is of 20 weeks duration, and phases 4 and 6 are of 10 weeks duration each.

Phase 1, Phase 3, Phase 5 and Phase 7 are delivered "on the job" in the apprentices' place of employment.

Fuel oil used by most plant machinery.

Rudolf Diesel

The fuel gets its name from Rudolf Diesel, the man who produced the first compression ignition engine whilst working for MAN in Augsburg, Germany, in 1897.

This is the unit of electrical force that pushes electrons around a circuit. This force can be small, as in the case of plant vehicles-12 volt or 24 volt, or it can be large, as in the mains electricity in a workshops-110 volt, 220 volt or 380 volt.

Ampere (often abbreviated to amps) is a measure of the rate at which a given amount of electricity flows in a circuit. This term is commonly shortened to amps.

When one coulomb of electricity has passed a given point in a circuit in one second, one ampere of electricity is said to have passed.

This figure gives us no indication of what force is pushing the electrons (voltage), but it does tell us how much and at what rate the electricity is being pushed.

1 ampere is 1 coulomb per second.

This is a measure of the resistance in an electrical circuit, and it is measured in ohms.

The Greek letter Omega, Ω, is often used to represent resistance in electrical circuits.

Word formed by using the first letter of other words, for example:

RAM-Random Access Memory

:

The alt or alternative key on a computer.

Short for "Alternate" key. The alt key on the keyboard allows other keys have a third function. For example, the "a" key will produce a lower case "a" when used on its own. If it is pressed in conjuction with the shift key, it produces a capital "A". The alt key when used in conjuction with the "a" key would allow it to produce some new programmable function.

:
Brake Horse Power: The amount of power that is available at the flywheel of an engine. Power is generated in the combustion chambers, but due to mechanical inefficiencies and losses, not all the power becomes available at the flywheel. The amount of power at the flywheel is measured by running the engine against some form of absorbtion brake, hence the term BRAKE Horsepower.
:
A binary digit, either a 1 or a 0.  The word "bit" is formed from these 2 words-binary digit = bit
