Scope Multimeter
The Scope Multimeter function allows you to perform multiple types of circuit and component
measurement tests. This chapter includes general operation procedures, instructions for saving
and reviewing test data, optional settings, and general reference information.
5.1 Overview
The Scope Multimeter test functions are:
•
Digital Multimeter (DMM)
•
Graphing Multimeter (GMM)
•
Lab Scope
5.1.1 Digital Multimeter (DMM)
The digital multimeter gives you the ability to quickly make precise common electrical
measurements (e.g. DC and AC voltage, resistance and amperage) on circuits and components
to verify operation. The meter displays measurements in a digital numerical format, and is typically
used for measuring signals that are not rapidly changing.
The DMM is ideal for performing basic tests on most standard automotive circuits, and displays
the results in a large easy to see format.
To use the DMM, select the
Scope Multimeter
icon from the home screen then select
Digital
Multimeter
from the menu. See
Tests and Capabilities (Quick Reference)
‚ on page 33 for a list of
available testing functions.
