A five (5) lesson library. The library describes megohmmeters, Wheatstone bridges, and clamp-on ammeters.
Ammeters, Meggers, and Wheatstone Bridge Library
The library describes megohmmeters, Wheatstone bridges, and clamp-on ammeters. It gives examples of the use of these instruments, identifies their components, and defines their functions. The lessons also describe safety and selection considerations for their use, how to set up the instruments, how to connect them to the systems under test, and how to take and read measurements.
Learn about the basic concepts behind and usage of megaohmeters, wheatstone bridges, and ammeters. Take and read measurements and set up instruments.
AMMETERS MEGGERS AND WHEATSTONE BRIDGE
This is the first lesson in the iKNOW™ Ammeters, Meggers, and Wheatstone Bridge Library. This lesson explains Ohm’s Law and how it is used when analyzing test results. The basic components, uses, and functions of a megohmmeter are described. Insulation and causes of insulation damage are also covered.
This is the fourth lesson in the iKNOW™ Ammeters, Meggers, and Wheatstone Bridge Library. This lesson explains how to balance a Wheatstone bridge and the process used to set mechanical and electrical zero. How to interpret the readings of a Wheatstone bridge is also explained.
This is the final lesson in the iKNOW™ Ammeters, Meggers, and Wheatstone Bridge Library. This lesson presents the components and features and functions of clamp-on ammeters. The lesson also describes safety considerations that should be noted when selecting a clamp-on ammeter. Instruction in the procedures for setting up, taking readings, and modifying the range of a clamp-on ammeter are also covered.
