  • Why You should take this seminar

    Understand the basics of electricity generation and delivery. Learn how to effectively diagnose electrical control circuit problems. The terms voltage, curent, and impedance (resistance) will become standard in your electrical conversations. Participants will experience live circuit faults in a real world, hands-on scenario so you can become a confident and safe troubleshooter.  Learn to safely use the proper measurement instruments and tools to understand the characteristics and properties of electrical signals.

    This 4-day industrial electrical troubleshooting seminar allows you to work hands-on with the same control circuits and devices commonly used on HVAC systems, pump systems, hydraulics, conveyors, and automated machines.
