The purpose of the EN50160 standard Voltage characteristics of electricity
supplied by public distribution systems is to specify the characteristics of the
supply voltage with regard to the course of the curve, the voltage level, the
frequency, and symmetry of the 3-phase network at the interconnecting point to
the customer. The goal is to determine limiting values for regular operating
conditions.
However, facility defects may lead to major disturbances in the electricity
distribution supply network. Accordingly, the standard establishes these values as
limiting values, which are not allowed to be exceeded on the high or low side
during 95% of the controlled period typically one week.

Configure and start an EN50160 test of line quality. It is recommended that a
brief test of 10 minutes or longer be done first, to verify the connections and
parameters of the test are correct. Only then should the 1-week test be done.
If neither of the voltage profiles are chosen, a field appears to enter the nominal
voltage. The frequency is not asked for, since it will be asked for when the test
result is downloaded.
Follow the instructions in the dialog box to setup and run this special test. Press
Help for further instructions.
Run the Test After configuring the instrument, press OK. The status window will display if a
recording is ready to start.

TIP Always use the EN50160 data screen when downloading an EN50160
recording, NOT the recording screen.
