Abstract

Systems and method for increasing current monitor accuracy are disclosed. The systems and methods may include receiving a run-time load value from a current monitor, determining a component parameter value associated with the run-time load value, and communicating the component parameter value to the current monitor.

Claims

1. An information handling system for increasing current monitor accuracy, the system comprising a node manager communicatively coupled to a current monitor, the node manager configured to:

receive a run-time load value from the current monitor;

determine a component parameter value associated with the run-time load value; and

communicate the component parameter value to the current monitor.

2. The system of claim 1, wherein the run-time load value comprises a statistically analyzed set of load values.

3. The system of claim 2, wherein the statistically analyzed set of load values comprises an average of load values over a period of time.

4. The system of claim 1, wherein the node manager comprises a lookup table, the lookup table comprising the run-time load value and the component parameter.

5. The system of claim 1, wherein the run-time load value is a load range.

6. The system of claim 1, wherein the component parameter value is an amplifier gain value.

7. The system of claim 1, wherein the current monitor comprises an adjustable component, the adjustable component configured to incorporate the component parameter value into a changed setting.

8. The system of claim 7, wherein the adjustable component is an analog-to-digital converter.

9. A method for increasing current monitor accuracy, the method comprising:

receiving a run-time load value from a current monitor;

determining a component parameter value associated with the run-time load value; and

communicating the component parameter value to the current monitor.

10. The method of claim 9, wherein the run-time load value comprises a statistically analyzed set of load values.

11. The method of claim 10, wherein the statistically analyzed set of load values comprises an average of load values over a period of time.

12. The method of claim 9, wherein determining the component parameter value associated with the run-time load value comprises determining the component parameter value from a lookup table, the lookup table comprising the run-time load value and the component parameter.

13. The method of claim 9, wherein the run-time load value is a load range.

14. The method of claim 9, wherein the component parameter value is an amplifier gain value.

15. The method of claim 9, wherein the current monitor comprises an adjustable component, the adjustable component configured to incorporate the component parameter value into a changed setting.

16. The method of claim 15, wherein the adjustable component is an analog-to-digital converter.
