The Sonel PQM-711 features a built-in GPS receiver, which ensures real-time clock accuracy, and integrates a 4G LTE GSM modem for convenient use in remote analyzers. Additionally, the Sonel PQM-711 is equipped with a transient recorder (with a sampling frequency of 10 MHz and a voltage range of up to ±8000 V).

Another ace of the analyzer is its built-in Wi-Fi communication module, which offers several advantages: unrestricted file transfer, no data transmission costs, and the use of local wireless infrastructure... This enables users to adapt to the common conditions on site. They can use laptops, smartphones or tablets to monitor the measurements from a convenient location (for example, an area free from electromagnetic interference) from a comfortable position.

The Sonel PQM-711 can be operated using a touchscreen computing device equipped with the Sonel Analysis software (for Windows) or the Sonel Analysis mobile application (for Android). Users can monitor the measurements and conduct diagnoses while maintaining mobility - they don't even need to be close to the analyzer. In typical applications, this device acts as a remote display and intermediate storage for measurement data, with the functionality of a router. Therefore, users can also connect to it via a wireless network - for example, transmitting the collected registrations to a desktop computer.

The Sonel PQM-711 is widely used in the professional power industry. It offers a complete 4-quadrant analysis, meeting the needs of energy consumers and producers, such as renewable energy sources, including photovoltaic and wind farms. It can predict faults in the distribution network. It provides analysis of the network and the load capacity of transformers, and records their current status. Moreover, it is a powerful investment tool. With the Sonel PQM-711, users will obtain the data needed for the development of power infrastructure, predict potential problems, and finally verify the correctness and quality of the implementation.
