Abstract

A digital multimeter stores multiple sequential measurements of physical or electrical parameters. Each of the sequential measurements has a name including an automatically generated descriptor. The descriptor for each sequential measurement may indicate a relative position of the measurement within the sequence. For instance, the descriptor may indicate whether the measurement was obtained before or after other measurements in the sequence.

First claim

The invention claimed is:

1. A handheld device for detecting electrical or physical parameters, comprising:
a measurement component that measures physical or electrical parameters;
a user interface configured to receive an activation input that activates automated saving of subsequent successive stable measurements measured by the measurement component; and
a processor coupled to the measurement component and the user interface, wherein, responsive to receipt of the activation input by the user interface, the processor:
displays a plurality of subsequent successive stable measurements measured by the measurement component, wherein each measurement determined to be stable is displayed until a further subsequent measurement is determined to be stable; and
automatically stores each measurement of the plurality of displayed subsequent successive stable measurements in a memory communicatively coupled to the processor,

wherein the user interface is further configured to receive a review input, and responsive to receipt of the review input by the user interface, the processor retrieves a plurality of previously-stored stable measurements and provides a user-selective display of the stable measurements for review by a user.

2. The handheld device of claim 1 , wherein:
the user interface is further configured to receive a stop input that deactivates the automated saving of subsequent successive stable measurement results, and
responsive to receipt of the stop input by the user interface, the processor deactivates the automated storing of the plurality of subsequent successive stable measurements in the memory.

3. The handheld device of claim 1 , wherein the plurality of subsequent successive stable measurements measured by the measurement component are individually and successively displayed as each measurement is determined to be stable.

4. The handheld device of claim 1 , wherein the plurality of previously-stored stable measurements are displayed in an order according to the sequence in which the measurements were determined to be stable and stored in the memory.

5. The handheld device of claim 4 , wherein the processor associates an automatically incrementing number with each displayed stable measurement measured after the automated saving has been activated.

6. The handheld device of claim 5 , wherein the processor individually and successively displays each measurement of the plurality of subsequent successive stable measurements with the respective automatically incremented number associated therewith.

7. The handheld device of claim 5 , wherein the processor stores each measurement of the plurality of displayed subsequent successive stable measurements with the respective automatically incremented number associated therewith.

8. The handheld device of claim 7 , wherein:
the user interface is further configured to receive an identifier to be associated with the subsequent successive stable measurements measured by the measurement component, and
the processor associates the identifier with the plurality of displayed subsequent successive stable measurements stored in the memory.

9. The handheld device of claim 8 , wherein responsive to receipt of the review input by the user interface, the processor displays the plurality of previously-stored stable measurements with the identifier and the respective automatically incremented numbers associated therewith.

10. The handheld device of claim 1 , wherein:
the user interface is further configured to receive an identifier to be associated with the subsequent successive stable measurements measured by the measurement component, and
the processor associates the identifier with the plurality of displayed subsequent successive stable measurements stored in the memory.

11. The handheld device of claim 10 , wherein responsive to receipt of the review input by the user interface, the processor displays the plurality of previously-stored stable measurements with the identifier associated therewith.

12. The handheld device of claim 1 , wherein:
the user interface is further configured to receive a redo input to replace a previously-stored stable measurement with a new stable measurement, and
responsive to receipt of the redo input by the user interface, the processor stores a new stable measurement in the plurality of subsequent successive stable measurements in place of the most recently stored measurement.

13. The handheld device of claim 12 , wherein pending replacement of the most recently stored stable measurement, the processor causes a display of the most recently stored stable measurement to blink.

14. The handheld device of claim 1 , wherein:
the user interface is further configured to receive a replace input to replace a previously-stored stable measurement with a new stable measurement, and
responsive to receipt of the redo input by the user interface, the processor stores a new stable measurement in the plurality of subsequent successive stable measurements in place of a user-identified previously-stored measurement.

15. The handheld device of claim 14 , wherein the new stable measurement is stored with the plurality of subsequent successive stable measurements in the same sequential position in which the previously-stored stable measurement was stored.

16. The handheld device of claim 14 , wherein the user interface includes navigation inputs that are usable to identify the previously-stored stable measurement in the plurality of subsequent successive stable measurements.

17. The handheld device of claim 14 , wherein the new stable measurement is stored in the memory with a same identifier and/or autoincremented number previously associated with the previously-stored stable measurement.

18. The handheld device of claim 1 , wherein:
the user interface is further configured to receive a redo input to replace a user-identified previously-stored stable measurement with a new stable measurement, and
responsive to receipt of the redo input by the user interface, the processor discards the user-identified previously-stored stable measurement and all stored measurements subsequent to user-identified previously-stored stable measurement, and stores the new stable measurement in the plurality of subsequent successive stable measurements in place of the user-identified previously-stored stable measurement.

19. The handheld device of claim 18 , wherein:
each measurement in the plurality of subsequent successive stable measurements is stored in the memory with an automatically incrementing number,
the previously-stored stable measurement is identified by user-selection of the automatically incremented number associated with the previously-stored stable measurement, and
responsive to receipt of the redo input by the user interface, the processor discards all stored stable measurements having an associated automatically incremented number equal to or higher than the automatically incremented number associated with the identified previously-stored stable measurement.

20. A handheld device for detecting physical or electrical parameters, comprising:
a user input component that receives:
(i) a user selection of an input that activates automatic storage of subsequent successive stable measurements as a set if measurements in a memory;
(ii) an identifier to be associated with the set of measurements;

a measurement circuit configured to measure physical or electrical parameters; and
a processor coupled to the measurement circuit, the user input component, and
