Function mode change
Output voltage exceeds 100V. It occurs if you change the output value that is below
100V to the new value above 100V.
Calibrator is overloaded.
Changing some parameters of output signal (P Harmonic, etc.)
Changing frequency for voltage above 280V
Energy counting is finished.
Output voltage exceeds 280V while current outputs are floating. It occurs if you change
the output value that is below 280V to the new value above 280V and current outputs
