APPENDIX I GLOSSARY

AI-2 FORWARD RESISTANCE—The smaller resistance value observed when you are checking the forward resistance of a semiconductor. FREQUENCY METER—An instrument used to measure the rate at which ac voltages are generated. GALVANOMETER—A meter used to measure small values of current by electromagnetic or electrodynamic means. GENERAL PURPOSE ELECTRONIC TEST EQUIPMENT (GPETE)—Test equipment that has the capability, without modification, to generate, modify, or measure a range of electronic functions required to test two or more equipments or systems of basically different designs. INDUCTANCE BRIDGE—An ac bridge circuit used to measure an unknown value of inductance. MAINTENANCE—Work done to correct, reduce, or counteract wear, failure, and damage to equipment. MEASURE (Metrology Automated System for Uniform Recall and Reporting)—A Navy standardized system designed to provide the recall, scheduling, and documenting of test equipment into calibration facilities. MECHANICAL-ROTATION FREQUENCY—The speed in revolutions per minute of armatures in electric motors and engine-driven generators; blade speed in turbines. MEGGER—A meter used to measure insulation resistance. METER MOVEMENT—The part of the meter that moves to indicate some electrical value. METER SHUNT—A resistor placed in parallel with the meter terminals; used to provide increased range capability. OHMMETER—A meter used to measure resistance. POWER FACTOR—An indication of the various losses of a capacitor, such as current leakage and dielectric absorption. PREVENTIVE MAINTENANCE—Consists of mechanical, electrical, and electronic checks; used to determine whether or not equipment is operating properly. SCAT CODES—A four-digit subcategory code used to identify the functional measurement parameters that can be satisfied by any one of many pieces of test equipment. SELF-EXCITED METER—A term used to describe meters that operate from their own power sources. SENSITIVITY—(1) For an ammeter, the amount of current that will cause full-scale deflection of the meter. (2) For a voltmeter, the ratio of the voltmeter resistance divided by the full-scale reading of the meter; expressed in ohms per volt. SCLSIS (Ship Configuration and Logistics Support Information System)—This encompasses the automated data processing system and all practices and procedures used for identification and status accounting of ship's configuration, logistics, technical data reviews, and equipment configuration audits. SHORT CIRCUIT—An unintentional current path between two components in a circuit or between a component and ground; usually caused by a circuit malfunction.
