Abstract

A system and method of measurement and processing of physical variables, and in particular electrical variables, comprising: a multimeter to measure multiple electrical variables, similar to any conventional multimeter; a microcomputer capable of the numerical processing of variables, storage and communication; a conventional computer that can read magnetic or optical storage media, or alternately, be connected to the Internet; an Internet website of public access to users of said multimeter; an Internet server which runs mathematical processing software to carry out graphical and numerical analysis.

Claims

1. A method of measuring, processing, and analyzing electrical variables to solve an operational or production problem, wherein said method comprises the steps of:

selecting an electrical variable to measure with a multimeter;

connecting the multimeter to a computer using a communication port available in the computer, through a communication cable;

selecting a measurement functionality from a storage media of the computer or an Internet site storing a plurality of measurement functionalities;

loading the selected measurement functionality from the computer into the multimeter;

configuring specific parameters of the selected measurement functionality using the computer;

disconnecting the multimeter from the computer;

measuring electrical variable data using the multimeter loaded with the selected measurement functionality;

connecting the multimeter to the computer;

transferring the measured electrical variable data from the multimeter to the computer;

transferring the measured electrical variable data from the computer to a server accessible via the Internet;

storing the measured electrical variable data on the server, wherein the stored electrical variable data is made publicly available via the Internet; and

executing application software in the server to process the stored data and to generate a first report including a statistical analysis of the stored data, the first report identifying an operational or production problem based on the statistical analysis and identifying a potential solution to the problem.

2. A method according to claim 1, wherein the stored data is processed by graphical processing using one or more programs resident on the server which generate a diagnosis report with a pre-defined format and a set of graphs whose format is defined by a user of the multimeter.

3. A method according to claim 1, wherein the stored data is processed by numerical processing using one or more programs resident on the server which process the data and convert it into new sets of data corresponding to at least one of statistics, correlations, maximums, and minimums to be incorporated into the first report.

4. A method according to claim 1 to validate the first report, comprising the steps of:

measuring the same electrical variable data using the multimeter as in claim 1;

transferring the newly measured electrical variable data from the multimeter to the computer;

transferring the newly measured electrical variable data from the computer to the server;

storing the newly measured electrical variable data on the server, wherein both the stored electrical variable data and the newly stored electrical variable data are made publicly available via a single Internet website;

executing application software in the server to process the newly stored data; and

generating, with the application software, a second report and comparing the second report with the first report to validate the one or more applied recommendations.

5. A method according to claim 1, wherein the first report is made publicly available via a published Internet web site.

6. A method according to claim 5, wherein the published Internet web site permits Internet users to post questions related to the analyzing of the measured electrical variable data and to answer questions posted by other Internet users or to post a diagnosis according to their experience.

7. A method according to claim 1, further comprising:

posting a question to the Internet site using the application software in the server, the question related to the identified operational or production problem; and

receiving one or more replies from Internet users comprising one or more potential solutions to the problem.

8. A method according to claim 7, further comprising applying one or more of the potential solutions received from the first report or the Internet users to solve the operational or production problem.

9. A method according to claim 1, wherein the operational or production problem includes optimizing the efficient use of electrical energy.
