{ "item_title" : "Multimeter Troubleshooting for Maintenance Technicians", "item_author" : [" Dovydas Kersys "], "item_description" : "Troubleshooting industrial electrical faults becomes much easier when you know exactly where to place your multimeter probes-and what the readings actually mean.Multimeter Troubleshooting for Maintenance Technicians is a practical, hands-on guide for maintenance technicians, electricians, industrial mechanics, and automation professionals who want to diagnose electrical problems faster and with less guesswork.Rather than focusing on complicated electrical theory, this book shows how to use a digital multimeter in real maintenance situations. You will learn how to follow circuits, compare expected and actual measurements, identify where voltage disappears, find high-resistance connections, test components, and narrow down faults step by step.Inside, you will learn how to troubleshoot: AC and DC voltage circuits24 VDC industrial control systemsFuses and circuit breakersPushbuttons, switches, and emergency-stop circuitsRelays and contactorsSolenoid valve coilsProximity and other industrial sensorsPNP and NPN sensor circuitsPLC inputs and outputsThree-phase motor circuitsMotor windingsControl transformers4-20 mA signals0-10 V analog signalsVariable-frequency drive control circuitsPotentiometers and heating elementsGround, common, and wiring faultsIntermittent electrical problemsLoose terminals and damaged connectorsYou will also learn practical troubleshooting methods such as voltage-drop testing, working from the load backward, working from the source forward, and using the half-split method to quickly narrow down long control circuits.The book includes practical examples, troubleshooting flowcharts, electrical diagrams, quick-reference tables, diagnostic exercises, and real-world fault scenarios designed to help you build stronger troubleshooting habits.Whether you are new to industrial maintenance or already have years of experience, this guide will help you use your multimeter more confidently, avoid unnecessary component replacement, and find electrical faults more systematically.Stop guessing. Follow the circuit, measure the right points, and let the readings lead you to the fault.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/819/227/9798192270684_b.jpg", "price_data" : { "retail_price" : "10.99", "online_price" : "10.99", "our_price" : "10.99", "club_price" : "10.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
