8.13.- RECORDING FILES
QNA500 power quality analyzer records different files, in accordance with the type of data (voltage,
events, energy, etc).
The power quality analyzer records the following files:
8.13.1.- .STD FILE
The Standard File (STD) is used to store all parameters that are stored periodically.
The records will be stored with the following electrical parameters (depending on the selection),
respecting the recording period programmed with the analyzer:
