Textbook Question
Chapter 42, Problem 1RQ
What are the three main electrical test instruments used in troubleshooting?
Expert Solution & Answer
To determine
Three main electrical test instruments used in trouble shooting.
Explanation of Solution
An industrial electrician's main job is to troubleshoot or restore a control circuit when it fails. First, it is necessary to determine which component is at fault in order to repair or remove a faulty component. Three main instruments used to troubleshoot a circuit are the voltmeter, ohmmeter, and ammeter. They can measure several different electrical quantities, so this meters are called multimeters.
Thus Voltmeter, Ohmmeter, Ammeter are the main electrical test instruments used in trouble shooting.
