Abstract

A digital multimeter provides information regarding measurements shown on a display of the multimeter, and available functions of the multimeter. The information typically relates to a current context of the multimeter. The context may include a current mode or other setting of the multimeter.

Claims

1. A portable digital multimeter, comprising:

a display configured to display measurement values and available functions of the multimeter;

a user interface configured to receive a user input indicating a request for context-sensitive explanatory information regarding the measurement values or the available functions;

a memory configured to store context-sensitive information relating to the measurement values or the available functions;

a processor configured to;

in response to receiving the user input, retrieve the context-sensitive information from the memory to allow the information to be shown on the display; and

receive from a user custom context-sensitive explanatory information for user specific requirements regarding the displayed measurement values or available functions of the multimeter for storage in the memory and for re-programming previously stored.

2. The portable digital multimeter of claim 1, wherein the processor further controls the display to present the information in a pop-up dialog box.

3. The portable digital multimeter of claim 2, wherein the pop-up dialog box includes a title bar displaying information regarding the multimeter functions in operation at the time when the user input was received.

4. The portable digital multimeter of claim 2, wherein the pop-up dialog box displays indications of the available functions of the multimeter and text explaining the operation of the corresponding functions.

5. The portable digital multimeter of claim 2, wherein the pop-up dialog box has an associated scrolling mechanism for allowing a user to scroll through information within the pop-up dialog box.

6. The portable digital multimeter of claim 2, wherein when the pop-up dialog box is displayed, the processor further controls the display to present a smaller version of the measurement value that was presented on the display immediately prior to the display of the pop-up dialog.

7. The portable digital multimeter of claim 1, wherein the information comprises instructions for performing one or more measurements with the digital multimeter.

8. The portable digital multimeter of claim 1, wherein the information includes a description of a mode of the multimeter.

9. The portable digital multimeter of claim 1, wherein the user input is received in response to actuation of a single button or switch on the multimeter.

21. The portable digital multimeter of claim 1, wherein the context-sensitive explanatory information is customized in response to a customization user input.

22. The portable digital multimeter of claim 1, wherein the user interface includes a navigation tool for indicating on the display the measurement value or function for which context-sensitive explanatory information is requested.

10. A portable digital multimeter, comprising:

a display configured to display measurement values and available functions of the multimeter;

a user interface configured to receive a user input indicating a request for context-sensitive explanatory information regarding the measurement values or the available functions;

a memory configured to store the context-sensitive explanatory information;

a processor configured to;

in response to receiving the user input, retrieve from the memory the context-sensitive information to be shown on the display; and

download to the memory user customized context-sensitive explanatory instruction from an external electronic storage medium for re-programming previously stored context-sensitive explanatory information regarding the displayed measurement values or available functions of the multimeter.

11. The portable digital multimeter of claim 10, wherein the user customized context-sensitive explanatory instruction is reconfigurable for user specific requirements.

12. A method of displaying information on a portable digital multimeter, the method comprising:

receiving a user input, wherein the user input indicates a request for information regarding available functions of the multimeter or visual elements displayed on the display screen;

in response to receiving the user input, retrieving information from a memory regarding the available functions or visual elements;

causing to be displayed the retrieved information; and

receiving customized information for user specific requirements regarding the available functions or visual elements displayed on the display screen of the multimeter for storage in the memory and for re-programming previously stored information regarding available functions of the multimeter or visual elements displayed on the display screen.

13. The method of claim 12, further comprising displaying the information in a pop-up dialog box on a display screen.

14. The method of claim 13, wherein the pop-up dialog box comprises a title bar, which includes information regarding the multimeter functions in operation at the time when the user input was received.

15. The method of claim 13, wherein the pop-up dialog box shows the indications of the available functions of the multimeter and text explaining the operation of the corresponding functions.

16. The method of claim 13, wherein the pop-up dialog box has an associated scrolling mechanism for allowing a user to scroll through information within the pop-up dialog box.

17. The method of claim 13, wherein when the pop-up dialog box is displayed, the processor further controls the display to present a smaller version of a measurement value presented on the display immediately prior to the display of the pop-up dialog.

18. The method of claim 12, wherein indications of the available functions of the multimeter comprise graphical icons presented in the display.

19. The method of claim 12, wherein the information is context-sensitive explanatory information and comprises instructions for performing a series of measurements with the digital multimeter and an explanation of a current mode of the multimeter.

20. The method of claim 12, wherein the user input is received in response to actuation of a single button or switch on the multimeter.

23. The method of claim 12, further comprising reconfiguring the information for user specific requirements.

24. The method of claim 12, further comprising indicating on the display screen available functions or visual elements for which context-sensitive explanatory information is requested.
