First of all, about the device itself. The electronic caliper serves as a digital counterpart to a familiar measuring instrument with a nonius, sliding legs and a slider. Anyone who used digital gauges had to evaluate their ultimate functionality. It is enough to direct, position or attach this outlandish electronics to the object of measurement, and the measured parameter will appear on the display. There is no need to break the eye of limbs and digital scales with dashes and numbers. At once it is necessary to make a reservation that such a method is ideal for a large work flow, when a huge amount of measurements is required.
Immediately about the features: the electronic caliper is equipped with a liquid crystal display, has three buttons, and this is enough to solve a wide range of tasks. Judge for yourself:
- power button, everything is clear without comments;
- the ability to switch scales from inch to metric;
- calibration of the origin, here lies the beauty of the device.
The fact is that a digital caliper can also show negative values. What is the calibration button for? Prior to the start of work, the legs of the device are closed, the button is pressed, the device shows zero - you can begin to measure.
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 abnormalities on the screen, positive or negative. It is very, very save time when collecting statistics. Some models have an option to automatically turn off the display, which will help save batteries, but that's not all.
In addition to the automatic mode, it is possible to monitor the readings of the device visually, since traditional measuring scales with dashes and numbers are applied to the pen. To work, you will need several 1-volt “tablet” batteries. It must be remembered that liquid crystal displays do not tolerate severe frost. What can be measured? Repeating the capabilities of traditional models, electronic caliper allows you to measure:
- linear dimensions and diameters;
- internal diameters.
Two pairs of legs provide measurement of these two groups of parameters with a device such as a caliper.
How to use this tool? The device must first be turned on, then it is calibrated, for this it is necessary:
- close the jaws of the device;
- press the calibration button.
To measure an object, a linear dimension or diameter is captured between the large legs, the measurement result appears on the display. Small feet measure the inner diameter. They are inserted inwards all the way into the hole walls, the resulting value can be read on the screen.
The electronic caliper is relatively inexpensive, the simplest model range can offer modifications for as low as $ 10. Is it worth it to make their lives easier, everyone can decide for himself.
