It is known that it is most convenient to use reference electricity meter , which is essentially a portable multifunctional device. Modern calibration meters are capable of operating both completely autonomously and after being connected to a personal computer or other digital device. In the latter case, the verification counter is operated much easier and more efficiently, since it uses special software.
Types of reference counters
For the most part, reference meters can be presented in three main variations:
1. Miniature portable means for verification;
2. Working standards;
3. Primary state standards.
Depending on the type chosen, reference counters can effectively perform the specified functions.
The most demanded version of reference counters
So, in the laboratories of IDGC, at meteorological stations, as well as at those enterprises where the meters are manufactured, the universal equipment of the UPPU-ME series is most often used. It is based on the most accurate or in other words reference electric power meters for AC or DC. It is important to note that it is the above-described type of meters for verification that is considered the most demanded, but it can also be subdivided into subspecies in direct dependence on the specific scope of application.
