Virtual Digital Caliper in Millimeter – Use Simulator

Use of the digital caliper in hundredth of millimeter

Resolution one-hundredth of a millimeter (0.01 mm) with switch to inch and zero 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.

Analog versus digital caliper, which to use?

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

The analog dial is what has pointers. It is analog, as we interpret the value of time comparing their position to the displayed and is a continuous function, so we put much of our ability to interpret this simple act.

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

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

Time is 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 dial allows interpret this information effortlessly. It dispenses to do the calculations.

Evaluated under that viewpoint, the analog caliper is preferable in production lines / machining, because it helps the professional to do the calculations on how much material must still be removed, for example. The dial caliper has a room in sections as of: quality control, inspection and metrology.

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

An electronic apparatus increases the distance traveled by the cursor and presents on a liquid crystal display. An advantage of this geometry is to allow the possibility to switch between the measure submitted, ten-inch milesimal proximate mm and fractional inch. Another advantage is the possibility to tune 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.

Digital caliper in hundredth millimeter

The digital caliper, as a rule, can not replace the micrometer with hundredth resolution because its accuracy (inaccuracy between displayed and actual value) is greater than the resolution (smaller measure as shown by an instrument). Of course, knowing these values, an experienced metrology can compensate for this deviation.

In the caliper simulator, drag and drop the cursor in the horizontal or use the button

Tips:

  • click in the botton “in/mm” to commute the measure between scales in millimeter and inch
  • click in the botton “zero” to reset the display in any point of the scale
  • drag the cursor to the right and to the left and investigate the results
  • click again to revert the situation
  • the screen resolution doesn’t allow  this instrument interpol each possibility of measure
