Instruction Manual
4.2.- MEASUREMENT PARAMETERS
The device measures and logs different types of parameters:
 Electrical parameters,
 Quality parameters (EVQ) such as overvoltages, gaps and outages, in accordance with
EN50160.
 Wave shapes of the different channels.
All the measurement parameters can be viewed on the MYeBOX mobile application, as shown
in Table 11.
