LM317T Voltage Regulator with Pass Transistor

A list of my multimeters can be purchased here: astore.amazon.com This series of videos is a tutorial on how to use a digital multimeter for beginners. It will also explain the basics of electricity and address some safety issues. This first video covers how to measure AC (alternating current) and DC (direct current) voltage. I use a Fluke 177 multimeter for this demonstration provided by Comtest: www.ComTest.co.za Items covered in this multimeter tutorial: * Multimeter safety * How to measure battery voltage; how to measure a car battery / lead acid battery; how to measure mains electricity / power outlet / 220 volt / 110 volt. * What is electricity; how does electricity work; what is voltage; what is current / amps / ampage / ampere.

In this video I do a basic demonstration of the Hantek DSO-1200 oscilloscope as well as the Fluke 43b oscilloscope function. I demonstate some of the functionality and trouble shooting around my solar powered Kindle DX project. I talk a about supercapacitors and show a nornal capacitor working in conjuction with a voltage regulator. Details: www.kmeasure.co.za Digital Oscilloscope Specifications: .
