Accuracy is a key element in every type construction project. Different measuring tools evolved throughout the years so you can easily gather details about angles, distances and everything else that can be measured. In this regard, Vernier Caliper Model is a simple application that aims to teach you how to use and read a caliper.

There's one thing you need to do before launching the application and that is to make sure your computer is equipped with Java Runtime Environment. Some consequences mean that it can run on any machine equipped with Java, the possibility to take it with you on a USB Flash drive, while the computer's state and health status remain intact, because registries are not tampered with.

As the name suggests, running the application gets you acquainted with a caliper tool. It's neatly displayed, with options to set anti-aliasing for text and visual elements to make everything smooth and clear. What's more, you can choose from several measurement versions for more possibilities.

The model is fully interactive, and you can enable hints and answers that help you learn how to properly read indicators. The bigger the main window, the larger the model and the coverage area, but don't worry about proportions and ratios, because they are kept intact for enhanced precision.

Moving the scale is done in several methods for both fast and accurate measuring. You can also zoom in and out, as well as switch to inside measuring. Both states put an object at your disposal of configurable size, but the exact value is not displayed, unless using the caliper to find out yourself.

One thing's missing though, and that is the possibility to set the window transparency in case there's an object on your desktop to measure. What you can do is save an image file of the current state, as well as a log of activities, but these are only code representations of what the application does, and not actual measurement values.

Taking everything into consideration, we can say that Vernier Caliper Model is a simple, straightforward, but practical application with which you can get familiar with a caliper tool. Modes and objects you interact with are neatly put at your disposal, and although it can't be used to measure desktop objects, it's still worth a try.
