Scale division

Scale division value. Initially, the term "scale division" referred only to mechanical devices (see "Mechanism") and meant the distance between divisions on a scale; however, out of habit, they began to use it for electronic scales. Moreover, both there and there the meaning of this parameter is the same — in fact, it directly describes the accuracy of measurements. For example, if the division value is 1 g, the weight on such devices can be measured with an accuracy of 1 g, regardless of whether it is a mechanical model or an electronic one.

Theoretically, the lower the division value, the more accurate the measurements and the more advanced the device is. On the other hand, high accuracy has a corresponding effect on the price, although in some situations it is not required in principle. So when choosing it is worth considering the features of the application of the device. For example, a kitchen scale with a division value of 0.5 – 1 g will be indispensable for a sophisticated cooker who cooks according to complex recipes with an abundance of ingredients in a small dosage; and for ordinary household cooking on a large scale, an accuracy of 10–20 g is quite enough. But there are also cases when, over the entire measurement range, the division value changes. So for more correct measurements (low weight), the accuracy can be measured in units of grams, for average values — in tens of grams, and already for heavyweights, where an er...ror of 50 – 100 grams is not so critical, even in hundreds of grams. In such cases, we have a value for the general average range in the catalog (if we take into account the floor, then this is approximately for a person of 70 kg).

Power source

The vast majority of electronic scales are powered by a battery pack. But some models may have a built-in battery, which does not require constant replacement. Just remember to recharge the scales.

Battery powered scales can use different types of batteries:

AA — the format of the classic "finger" batteries;

AAA — "microfinger" batteries;

CR2032 — the so-called coin type. Many PC users are familiar with this battery format. "Coins" are used to power BIOS memory in motherboards.

In addition to the type of batteries, you also need to pay attention to their number in the battery compartment.
