First of all about the device itself. The caliper electronic serves as a digital analogue to a conventional measuring device with a vernier, sliding legs and a slider. Anyone who used digital meters had to evaluate their ultimate functionality. It is enough to guide, arrange or apply this outlandish electronics to the measurement object, and the measured value appears on the display. There is no need to break your eye about limbs and digital scales with dashes and numbers. At once it is necessary to make a reservation that this method is ideal for a large workflow, when it is required to conduct a huge number of measurements.
Immediately on the features: caliper electronic 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:
- button inclusion, everything is clear without comments;
- the ability to switch scales from inch to metric;
- calibration of the origin, this is where the whole charm of the device lies.
The fact is that the digital caliper can also show negative values. Why do I need a calibration button? Before the work starts, the device's feet are closed, the button is pressed, the device shows zero - you can start measuring.
But! If there is a number of products with the same nominal size and you need to establish deviations from the norm of each of them, take your time. Clamp the legs on the reference product, press the calibration button - you're done! The reference part now corresponds to zero readings, and any other will give deviations from the norm, positive or negative, on the screen. This will save a lot of time when typing statistics. Some models have the option of automatically turning off the display, which will help to conserve batteries, but that's not all.
In addition to the automatic mode, you can monitor the instrument visually, since the handle is marked with traditional measuring scales with dashes and numbers. To work, you will need several 1-volt batteries - "tablets". It must be remembered that liquid crystal displays do not tolerate a strong frost. What can be measured? Repeating the capabilities of traditional models, caliper electronic allows you to measure:
- linear dimensions and diameters;
- internal diameters.
Two pairs of legs ensure the measurement of these two groups of parameters by means of a device such as a caliper.
How to use this tool? The device must first be switched on, then the calibration is performed, for this it is necessary:
- to close the sponges 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 inside diameter. They are inserted inward as far as the stop in the wall of the hole, the resulting value can be read on the screen.
The caliper electronic is relatively inexpensive, the simplest model range can offer modifications at a price of $ 10. Is it worth it to make your life easier, everyone can decide for himself.
