Main screen
This section describes the Main Screen functions. These functions are found on the left side
of the screen.
Time
• Start/Reset is the time when Flicker was started or reset. A Reset of Flicker causes
the Max/Min values to be cleared and restarts the Flicker Pst and Plt timers. A Start
of Flicker is also equivalent to a Reset in that the Pst and Plt are restarted and the
Max/Min Values are cleared.
• Stop corresponds to the time when Flicker is turned off.
• Current is the current clock time.
• Next Pst is the countdown time to when the next Pst value is available.
• Next Plt is the countdown time to when the next Plt value is available.
Status
• This screen indicates the current status: Active = On; Stopped = Off.
Frequency
• Base is the operating frequency (50 or 60 Hz) selected in the EN50160 Flicker
screen (see Section 12.3).
• Current is the real-time frequency measurement of the applied voltage.
Base Voltage
• This field shows the normalized voltage for the selected frequency (230 V for 50 Hz
or 120 V for 60 Hz).
