An ESD wrist strap is usually used with an ESD table mat on the workbench, or a static dissipating plastic laminate on the workbench. Screwdrivers 0:52-1:07 The next tool you'll need is a screwdriver. Either one screwdriver with interchangeable bits, or several screwdrivers of several different sizes. You might want to purchase a jeweler's screwdriver kit. Many internal components require very small screwdrivers, especially in laptops. Pliers 1:08-1:14

Pliers are used to grab those little screws that fall into the bottom of your computer case. This is probably the handiest tool of all. Extension Magnet 1:15-1:26 You'll also want an extension magnet to retrieve those little screws that inevitably fall into the system case as you're working on it. Just be careful working with any magnetized tool, because they can damage computer parts. 3-Prong Holder 1:27-1:33 Also, a three-prong holder is a tweezer-like tool with three prongs used for grabbing and lifting small objects. Multimeter 1:34-2:22 You'll need a multimeter. Some multimeters include a volt meter feature. A volt meter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale to show the voltage of the circuit. Digital voltmeters display a numerical value of the voltage by using an analog to digital converter. A multimeter is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter includes features like the ability to measure voltage. It can also test resistance and current flow. Some multimeters also test for capacitance, which is the ability of a component to retain a charge when the power is turned off, and simple continuity, which is the connection made between one end of the cable and the other. Power Supply Tester 2:23-2:59 Another way to test a power supply is with a power supply tester. A power supply tester is a version of a multimeter, so you can use either instrument to test your equipment. A power supply tester is used to make sure the correct voltage is coming out of your computer system's power supply. It is specifically designed to test DC voltage on most connections coming from a PC power supply. Let's test a power supply using the power supply tester. First, I'll insert the power cable, then I'll turn on the tester. This device is good. Tone Generator and Probe 3:00-3:29 A tone generator and a probe lets you trace a wire from a wall drop, an RJ-45 network jack, to a wiring closet. The tone generator emits a tone that goes along the wire, and is picked up by the probe.That's how you know which wire you are looking for. To use a tone generator and a probe, insert the tone generator RJ-45 connector into your data wall jack.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
