Abstract

A multimeter has a plurality of control panels, a display screen that can change display orientation, and/or a magnetic portion to releasably support the multimeter.

Claims

1. A multimeter, comprising:

a first set of controls configured to adjust a first measurement function of the multimeter;

a second set of controls configured to adjust a second measurement function of the multimeter; and

a display screen disposed on a first face of the multimeter;

wherein the first control panel and the second control panel are spatially separated by the display screen.

2. The multimeter of claim 1, further comprising a first input device and a second input device that are used for performing one or more measurement functions selected from the first control panel and the second control panel.

3. The multimeter of claim 2 wherein the first control panel and the first input device are located at a first end of the multimeter, and the second control panel and the second input device are located at a second end that is opposite to the first end of the multimeter.

4. The multimeter of claim 2 wherein at least one of the first input device and the second input device comprises a pair of test leads with extension wires.

5. The multimeter of claim 4, further comprising an input jack to directly connect a test lead without extension wire.

6. The multimeter of claim 2 wherein at least one of the first and second input devices comprises a non-contact type measurement sensor.

7. The multimeter of claim 1, further comprising:

a magnetic portion to magnetically support the display and the first and second sets of controls; and

a switch to turn ON and OFF the magnetic portion.

8. The multimeter of claim 1 wherein the display screen automatically changes its display orientation in response to selecting one of the first and second measurement functions so that the display can be conveniently read by the user.

9. An electrical measuring device, comprising:

a display showing a first measurement function in a first orientation and showing a second measurement function in a second orientation different from the first orientation.

10. The electrical measuring device of claim 9, further comprising a first control panel and a second panel.

11. The electrical measuring device of claim 10 wherein the first and second control panels are disposed on opposite sides of the display.

12. The electrical measuring device of claim 10, further comprising first and second input devices, the first input device is disposed on a first side of the display proximate the second control panel, and the second input device is disposed on a second side of the display proximate the first control panel.

13. The electrical measuring device of claim 9, further comprising:

a magnetic portion to magnetically support the display; and

a switch to turn ON and OFF the magnetic portion.

14. A multimeter comprising:

a magnetic portion including at least one magnet part and at least one magnetic conductive part, wherein the at least one magnet part and the at least one magnetic conductive part move relative to each other to switch the magnetic portion ON and OFF.

15. The multimeter of claim 14 wherein the magnet part and the magnetic conductive part turn relative to each other to switch the magnetic portion ON and OFF.

16. The multimeter of claim 14 wherein the magnet part and the magnetic conductive part translate relative to each other to switch the magnetic portion ON and OFF

17. The multimeter of claim 14, further comprising a magnetic conductive cover, wherein the magnet part is sandwiched between the magnetic conductive cover and the magnetic conductive part.

18. The multimeter of claim 14, further comprising a display screen, wherein the display screen automatically changes its display orientation between first and second orientations.

19. The multimeter of claim 14, further comprising first and second sets of controls to adjust a measurement function.
