Electrical monitoring system and assembly

A method of monitoring one or more systems of a vehicle, the method comprising:

• connecting one or more loop resistance test (LRT) ports of a single handheld monitoring system to the one or more systems;
• conducting a LRT of the one or more systems with the single handheld monitoring system;
• disconnecting the one or more LRT ports of the single handheld monitoring system from the one or more systems;
• connecting one or more network analysis ports of the single handheld monitoring system to the one or more systems;
• conducting a network analysis of the one or more systems with the single handheld monitoring system;
• disconnecting the one or more network analysis ports of the single handheld monitoring system from the one or more systems;
• connecting one or more time domain reflectometer (TDR) ports of the single handheld monitoring system to the one or more systems;
• conducting time domain reflectometry of the one or more systems with the single handheld monitoring system;
• disconnecting the one or more TDR ports of the single handheld monitoring system from the one or more systems,
• wherein the conducting the network analysis comprises analyzing results of the LRT, wherein the analyzing the results of the LRT comprises using the LRT to identify electrical characteristics of the one or more systems.

An electrical monitoring system configured to monitor one or more systems of a vehicle, the electrical monitoring system comprising:

• a single handheld housing;
• a loop resistance test (LRT) unit contained within the housing, wherein the LRT unit is configured to conduct loop resistance tests with respect to the one or more systems of the vehicle;
• one or more LRT ports extending into or from the housing, wherein the one or more LRT ports are coupled to the LRT unit and configured to connect to the one or more systems of the vehicle;
• a network analyzer contained within the housing, wherein the network analyzer is configured to conduct network analysis with respect to the one or more systems of the vehicle;
• one or more network analyzer ports extending into or from the housing, wherein the one or more network analyzer ports are coupled to the network analyzer and configured to connect to the one or more systems of the vehicle;
• a time domain reflectometer (TDR) unit contained within the housing, wherein the TDR unit is configured to conduct time domain reflectometry with respect to the one more systems of the vehicle;
• one or more TDR ports extending into or from the housing, wherein the one or more TDR ports are coupled to the TDR unit and configured to connect to the one or more systems of the vehicle;
• a communication unit configured to allow communication between the electrical monitoring system and a remote computing device that is separate and distinct from the single handheld housing;
• and
• a display retained by the housing, wherein the display is configured to present information related to the loop resistance tests, the network analysis, and the time domain reflectometry, wherein the LRT unit is configured to acquire LRT test data regarding the loop resistance tests, and wherein the network analyzer uses the LRT test data acquired by the LRT unit to identify electrical characteristics of the one or more systems.
