5.4.9. Flicker
This option permits to set control parameters relative to flicker value recordings on the
input voltages in compliance to IEC/EN61000-4-15 standard (see § 10.4). In particular the
below parameters are shown by meter:

Pst1’ = short term severity at 1 min.

Pst = short term severity for all recording duration.

Plt = long term severity for all recording duration.

The below screen is shown:
