This online engineering PDH course provides you some rudimentary understanding of the measuring instruments and demonstrates their correct and intelligent use.
When an electrical circuit is in operation, electricity flows through the wires and other objects in the circuit. Three basic parameters - current, potential difference (voltage) and resistance are of primary importance to achieve the desired functionality of electrical networks. Engineers concerned with design of electrical systems keep necessary provisions for in-circuit meters to monitor the operation of a piece of electric or electronic equipment and determine the reason the equipment is not functioning properly.
This 4 PDH online course is applicable to students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers who are interested in gaining a better understanding in circuit measurements.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- State two ways circuit measurement is used
- State how a d'Arsonval meter movement reacts to DC
- State the electrical quantity measured by ammeter, voltmeter, ohmmeter, megger, multi-meter and how these are connected to a circuit
- State the meaning of term "damping" as it applies to meter movements
- Identify three meter movements that measure DC or AC without use of a rectifier
- State the reason for using the highest range when connecting an ammeter to a circuit
- State the method used to allow a voltmeter to measure different ranges
- List the safety precautions for use of measuring instruments
- State two types of ohmmeters and the way in which each can be identified
- State the primary reason for using a megger and the method of using it
- State how a multi-meter differs from other meters and how a multi-meter is changed from a voltage measuring to a current measuring device
- State the purpose of hook-on type voltmeter and the two types of frequency meters
In this professional engineering CEU course, you need to review Chapter 1 of Module 3 titled "Circuit Measurement" of the Naval Education and Training Materials (NAVEDTRA 14175), Electricity and Electronic Training Series.
