Scope / Multimeter
The Scope Multimeter function allows you to perform multiple types
of circuit and component measurement tests. This section includes
general operation procedures, instructions for saving and
reviewing test data, optional settings, and general reference
information.

3.2 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
for a list of available testing functions.
