Learn How to Use Your Digital Multimeter in Electrical Troubleshooting

Print(printable outline)

In this program you will learn the basics of industrial electricity such as, what is current, voltage, resistance, and power. Some Ohm’s Law will be discussed along with magnetism. You will learn about Digital Multimeters that can measure Voltage, Resistance, and Current as well as Clamp-on Ammeters, and Capacitor Testers. You will then learn about control components such as transducers, capacitors, float switches, relays, alternators, potential relays, and phase monitors. There will be an in-depth look at reading the electrical control drawings used in the water treatment industry. You will learn about electric power distribution in your facility - Three Phase, Single Phase, Transformers, and Generation. Then you will move into a discussion on Electric Motors of all types and troubleshooting these motors. Motors are very simple to troubleshoot and we will show you how to determine if a motor is bad. We will wrap-up with a unique section we have created just for you called Troubleshooting Lift & Pump Stations. You will learn how to troubleshoot float switches, capacitors, phase monitors, alternators, pumps, and potential relays.
