Loopback Adapter. Loopback Adapter used to test the functionality of computer ports. PC Tools for Software and Hardware Trouble Shooting. These are the PC Tools and Components that will be used in PC Hardware and Software Trouble Shootings. A lens A ruler A T square A T square is a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table. It may also guide a set square to draw vertical or diagonal lines. Its name comes from the general shape of the instrument where the horizontal member of the T slides on the side of the drafting table. T squares come in varying sizes, common lengths being 1. T squares are also used to measure and cut drywall. Drywall T squares are typically made of aluminium and have a 4. Higher end table saws are often equipped with T square fences. These table saw fences are attached to a rail only on the front side of the table unlike traditional fences which clamp to both the front and the rear of the table. T square. Steel rules Steel rules come in rigid and flexible versions. While their primary purpose is accurate measurement, they can also be used as guides for laying out lines, and if rigid enough, for cutting. The thinner, more flexible rules can also be used to measure rounded or cambered work. The differences in the prices of rules result from the various production methods, which also determine accuracy and legibility. Most rules are made by cutting the required length from a roll of band spring steel, with etched graduations. Rules made by this method are adequate for most applications and reasonably priced. Higher priced rules are cut, not stamped, from plate steel stamping would cause the material to warp, and the edges are ground. Graduations are machined, much deeper than etched graduations, longer lasting, and easier to read in poor light. A protractor In geometry, a protractor is a square, circular or semicircular tool, typically in transparent perspex, for measuring angles. The units of measurement utilized are usually degrees . They are used for a variety of mechanical and engineering related applications, but perhaps the most common use is in geometry lessons in schools. Some protractors are simple half discs. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle. Protractor. An electronic calculator An electronic calculator is a small, portable, usually inexpensive electronic device used to perform the basic operations of arithmetic. Modern calculators are more portable than most computers, though most PDAs are comparable in size to handheld calculators. The first solid state electronic calculator was created in the 1. BC and the mechanical calculator, developed in the 1. It was developed in parallel with the analog computers of the day. Pocket sized devices became available in the 1. Intel for a Busicom calculator. Modern electronic calculators vary from cheap, give away, credit card sized models to sturdy desktop models with built in printers. They became popular in the mid 1. By the end of that decade, calculator prices had reduced to a point where a basic calculator was affordable to most and they became common in schools. Calculator. A multimeter A multimeter or a multitester, also known as a VOM Volt Ohm meter, is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current andresistance. Multimeters may use analog or digital circuits analog multimeters AMM and digital multimeters often abbreviated. DMM or DVOM. Analog instruments are usually based on a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made digital instruments usually display digits, but may display a bar of a length proportional to the quantity being measured. A multimeter can be a hand held device useful for basic fault finding and field service work or a bench instrument which can measure to a very high degree of accuracy. They can be used to troubleshoot electrical problems in a wide array of industrial and household devices such as electronic equipment, motor controls, domestic appliances, power supplies, and wiring systems. Multimeter. An eraser paint brushbrush 1  brshn. A device consisting of bristles fastened into a handle, used in scrubbing, polishing, or painting. The act of using this device.
