What to Look for Before Buying Best Astroais?
But those who do not have a great experience in the field risk spending their money badly if they are not careful to choose the right multimeter carefully, which provides the necessary data for the analysis and which no longer costs the intervention of the technician. If you don’t want to spend your money badly, the advice is to compare as many reviews as possible about the targeted models.
This is not the only way to have access to suitable tools to meet your needs, below we offer some of the best performing tools available on the market today.
A astroais is a useful tool that is used to obtain various measurements, among which the most common are those of voltage, current and electrical resistance. In its digital version, which we deal with on this page, the values are shown on an LED or LCD screen.
Let’s see together in this guide what are the discriminants and distinctive features of the models of the best brands so as to have all the information necessary to choose the perfect astroais to meet your needs. Then we will examine some particularly interesting models for the excellent relationship between performance and price.
Safety First
Being an appliance that must be used to collect electricity data, it is a good idea to ensure total safety and to be studied to avoid any possible risk during use. It is therefore essential that it is made with double insulation and with total protection of the entrances.
In particular it is important that the astroais meets the safety category relating to the type of voltage you will need to measure.
A higher category number (indicated with the abbreviation CAT) indicates how the appliance is able to withstand a higher energy level.
To perform a measurement on a 480 V electrical panel, for example, it is necessary to use an instrument compliant with category III, 600 V or 1,000 V. Within the same CAT, a higher voltage value ensures greater resistance to voltage transitional.
Generally speaking, the first rule to consider and which ranks first in the ranking of what you need to know before buying a astroais is that the higher category models are safer than the lower category ones.
The Importance of The Display
The astroaiss are divided into analog and digital, although technological development has led the producers to offer the market above all the latter even if, comparing the prices, they are more expensive.
In any case, the analog models are characterized by a needle that moves on a graduated indicator on which to read the various measurements.
It is easy to understand how these devices tend to be less precise, however, they maintain, in comparison with digital ones, the advantage of immediacy in grasping any signal variations.
The instruments with electronic screens allow you to enjoy impeccable precision as well as great ease of reading in any type of condition. Precisely the accuracy represents their added value because they are able to show at least three digits (if not more) for each measurement.
Finally, there are astroaiss that combine both functions and add an analog box to a digital display, so as to combine data precision but also the ability to grasp the variations on the fly.
Percentage of Accuracy
The aspect related to the precision of a measurement is very important and, when choosing a product of this type, you will always have to take into account the margin of error. By reading reviews and datasheets of astroaiss on sale on the market, therefore, you can easily identify this value which, usually, is defined as a percentage of the measurement.
An accuracy of 1%, for example, indicates that, if you get a value of 100 V, the real measurement is actually between 99 and 101 V. This error scale increases exponentially if you take into account the models analog, where the accuracy of the reading is largely given also by the operator’s eye and experience.
So if you approach a product of this type for the first time, our advice is to prefer a digital model, with an overvoltage category proportional to the type of measurements you will find yourself taking more often.
Complete and Functional
The DM01M is sold in a package together with four 1.5 Volt AA batteries, which are needed to power it, the red and black measuring cables with relative tips, a type K thermocouple for measuring the temperature and the complete instruction manual of Italian translation.
Being an inexpensive product, the quality of the accessories is just mediocre, and the Italian translation of the instructions is also a bit rough and lacking.
On the other hand, however, the English instructions are more understandable for those who are familiar with the language; replacing the measuring cables with a pair of higher quality, also significantly improve the performance of the device.
It can measure DC and AC voltage, resistance, capacitance, continuity of diodes, transistors, frequency and temperature without any problem; moreover it also has the additional function NCV, which allows to detect the voltage without contact, in order to identify the electric lines in the walls or under the floors.
Expandable with Other Optional Accessories
Its use is extremely simple and intuitive, both because all measurements are manageable thanks to a single control ring located in a central position, and because the buttons of the various functions are reduced in number and easily accessible. This feature makes it particularly suitable even for less experienced operators.
The display is large and backlit, with large numbers so that it can be read clearly even by those who wear glasses; in addition there is also a rear LED, very useful for illuminating switchboards or sockets when working in the dark.
