Last Brownout Values:
L1: Brownout Value=0.157, Duration=0.000 s,
Minimum (one-period) RMS value=216.1 V
L2: Brownout Value=0.298, Duration=0.020 s,
Minimum (one-period) RMS value=206.0 V
L3: Brownout Value=0.060, Duration=0.000 s,
Minimum (one-period) RMS value=219.2 V
The brownout value corresponds to the number of full 50 Hz cycles missing. Values below ~0.5 will generally not be a problem for most equipment.
Note that sometimes the browser needs a forced refresh (Shift-F5) to update the graphs.
