First of all, about the device itself . An electronic caliper serves as a digital analogue of a conventional measuring device with a vernier, sliding legs and a slider. Anyone who used digital meters should have appreciated their ultimate functionality. It is enough to point, position or attach this outlandish electronics to the measurement object, and the measured parameter will appear on the display. There is no need to break an eye on limbs and digital scales with dashes and numbers. Immediately you need to make a reservation that such a method is ideal for a large flow of work, when a huge number of measurements are required.
Just about the features: the electronic caliper is equipped with a liquid crystal display, has three buttons, and this is quite enough to solve a wide range of tasks. Judge for yourself:
- power button, everything is clear without comment;
- the ability to switch scales from inch to metric;
- calibration of the reference point, here all the charm of the device is hidden.
The fact is that the digital caliper can also show negative values. What is the calibration button for? Before starting work, the appliance paws are closed, a button is pressed, the appliance shows zero - you can start measuring.
But! If there are a number of products with the same nominal size and you need to establish deviations from the norm of each of them, do not rush. We close the legs on the reference product, press the calibration button - everything is ready! The reference part now corresponds to zero readings, and any other will give on the screen deviations from the norm, positive or negative. This will save a lot of time when collecting statistics. Some models have an option to automatically turn off the display, which will help conserve batteries, but that's not all.
In addition to the automatic mode, it is possible to control the instrument readings visually, since the traditional measuring scales with dashes and numbers are applied to the pen. To work, you need several 1-volt batteries, "tablets". It must be remembered that LCD displays do not tolerate severe frost. What can be measured? Repeating the possibilities of traditional models, the electronic caliper allows you to measure:
- linear dimensions and diameters;
- inner diameters.
Two pairs of legs provide measurement of these two groups of parameters by such a device as a vernier caliper.
How to use this tool? The device must first be turned on, then calibration is performed, for this it is necessary:
- close the jaws of the device;
- press the calibration button.
To measure an object, a linear size or diameter is captured between the large legs, the measurement result appears on the display. Small legs measure the inner diameter. They are inserted inward as far as the stop into the walls of the hole, the obtained value can be read on the screen.
An electronic caliper is relatively inexpensive, the simplest model range can offer modifications at a price of $ 10. Whether it’s worth it to make your life easier, everyone can decide for himself.
