Abstract

In addition to other aspects disclosed, a caliper is configured to measure at least one physical dimension. The caliper has a display configured to present a first representation and a second representation of a measurement provided by the caliper. The format of the first representation is different from the format of the second representation, and the first representation is approximately simultaneously displayed with the second representation.

Claims

1. An apparatus comprising:

a caliper comprising at least two jaws configured to measure a physical dimension;

a display configured to present a first representation of a measurement of the physical dimension, the first representation including a United States measurement unit presented as a decimal; and

a button for causing the display to toggle between presenting the first representation of the measurement and a second representation of the measurement, the second representation including the United States measurement unit presented as a fraction,

wherein the display is further configured to present a variance indicator representative of an approximate difference between the first representation of the measurement and the second representation of the measurement.

2. The apparatus of claim 1, wherein the display is configured to present a third representation of the measurement, the third representation including a metric measurement unit presented as a decimal.

3. The apparatus of claim 1, wherein a resolution of one or both of the first representation and the second representation is selectable.

4. The apparatus of claim 1, further comprising:

an electronics package that includes the display.

5. The apparatus of claim 1, wherein the display includes a unit indicator.

6. The apparatus of claim 1, further comprising:

an electronics package configured to provide data representative of the first representation and the second representation to an external display module.

7. The apparatus of claim 6, wherein a hardwire connection provides the data from the electronics package to the external display module.

8. The apparatus of claim 6, wherein a wireless connection provides the data from the electronics package to the external display module.

9. The apparatus of claim 1, wherein the at least two jaws include two outside jaws.

10. The apparatus of claim 9, wherein the two outside jaws are configured to measure an outside dimension of an object.

11. The apparatus of claim 1, wherein the at least two jaws include two inside jaws.

12. The apparatus of claim 11, wherein the two inside jaws are configured to measure an inside dimension of an object.

13. A method comprising:

on a display of a caliper configured to measure a physical dimension, toggling between;

a first representation of a measurement of the physical dimension, the first representation including a United States measurement unit presented as a decimal; and

a second representation of the measurement, the second representation including the United States measurement unit presented as a fraction,

wherein the display is configured to present a variance indicator representative of an approximate difference between the first representation of the measurement and the second representation of the measurement.

14. The method of claim 13, further comprising:

providing data that represents the first representation and the second representation to an external display module.

15. The method of claim 13, further comprising toggling between a third representation of the measurement, the third representation including a metric measurement unit presented as a decimal.

16. A computer program product, encoded on a computer-readable medium, operable to cause a data processing apparatus to perform operations comprising:

on a display of a caliper configured to measure a physical dimension, toggling between;

a first representation of a measurement of the physical dimension, the first representation including a United States measurement unit presented as a decimal; and

a second representation of the measurement the second representation including the United States measurement unit presented as a fraction,

wherein the display is configured to present a variance indicator representative of an approximate difference between the first representation of the measurement and the second representation of the measurement.

17. The computer program product of claim 16, further operable to cause the data processing apparatus to perform operations comprising:

providing data that represents the first representation and the second representation to an external display module.

18. The computer program product of claim 16, wherein the operations further comprise toggling between a third representation of the measurement, the third representation including a metric measurement unit presented as a decimal.
