## Using digital caliper in inch fractional

### Resolution 1/128″ with switch to millimeter and reset at any point

Digital caliper is a linear measuring instrument with a cursor that slides on a ruler. It is designed to take external linear measurements by contact. It can also measure internal dimensions, depths, ridges among others, dispensing the interpretation of the reading.

### Digital versus analog caliper, which one to use?

Each instrument has its highs and lows. I will contrast some of these points compared to the clocks (time markers) analog and digital.

The analog clock is what has pointers. It is analog, as we interpret the time value by comparing their position with the display and the display is a continuous function, so put a lot of our playability in this simple act.

The digital clock has no hands, we read the value of the time directly on the display. This approach eliminates the need to interpret the value of the time that is more uniform (regardless of who reads it) and requires less effort.

The foregoing paragraphs induces hasty conclusion that the digital clock is preferable to the analog clock. However, this conclusion is not, as a rule, the right one.

What time is it is a little relevant information for many people. Generally, what we want is to know how long before the time comes that interests us. How long before the end of the class or the beginning of the film session, for example. The analog clock allows interpret this information effortlessly. It dispenses us to do the calculations.

Evaluating in this light, the analog caliper is preferable in the lines of production / machining, because it helps the trader to make the material and calculations must also be removed, for example. The digital caliper has its space in sections such as: quality control, inspection and metrology.

### Virtual digital caliper

For reference, the scales of this simulator are graduated in millimeters and in decimal inch.

An electronic apparatus increases the distance the cursor and displays on a liquid crystal display. One advantage of this geometry is to allow the possibility to switch the measure presented between proximate millimeter, inch-tenth milesimal and fractional inch. Another advantage is the possibility to adjust the instrument at any point going to refer to the difference between the measurements, easing the tolerance inspection of various parts without the need to interpret each, for example.

The digital caliper, as a rule, can not replace the micrometer, since its accuracy (imprecision between presented and actual value) is greater than that of the resolution (smaller measure shown by an instrument).
