Ammeters, Meggers, and Wheatstone Bridge Bundle
About this class
A five (5) lesson library. The library describes megohmmeters, Wheatstone bridges, and clamp-on ammeters.
Prerequisites
This library is designed for participants familiar with AC/DC theory, electrical safety, and electrical print reading. A basic understanding of electronic devices and circuits is recommended.
Description
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.
Objectives
Learn about the basic concepts behind and usage of megaohmeters, wheatstone bridges, and ammeters. Take and read measurements and set up instruments.

Announcements
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.

Introduction to Megohmeters2013
This is the second lesson in the iKNOW™ Ammeters, Meggers, and
Wheatstone Bridge Library. This lesson describes safety issues to
consider when using a megohmmeter, how to select the correct megger for
the job, setup, and the steps necessary to take a megger reading.
-
This is the third lesson in the iKNOW™ Ammeters, Meggers, and Wheatstone
Bridge Library. This lesson explains what a bridge circuit is, the
purpose and components of a Wheatstone bridge, and its function.
-
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.
