We underline again that HPS automatically limits the maximum allowed current, avoiding damages
to the equipment; the only consequence is that, in this case, it is not guaranteed the precision of
the output waveform neither the accuracy of the output voltage.
The user can set the output voltage through the numeric keyboard, or he can continuously vary
the voltage through specific keys. The same possibility is valid for the setting of the frequency.
The above possibility makes the HPS very flexible in those applications where it is requested a
continuous variation of the two regulated magnitudes, around a given values.
