MODE Selects the mode of operation of output voltage: either AC only,
DC only, or AC with a DC offset. This selection also determines
the available output voltage ranges: 166/333 V(RMS) in AC and
220/440 VDC in DC mode. The output must be turned off to
change this setting. The default is AC.
Figure 5-179. Mode Settings
ALC Selects how the output voltage will be regulated; the default is
ALC on:
ON: The RMS digital regulator is enabled, and shutdown will be
executed if a loss of regulation occurs.
OFF: Regulation of the output voltage does not utilize the RMS
digital regulator, and shutdown that is dependent on regulation
would not occur.
Regulate: The RMS digital regulator is enabled, but shutdown
will not be executed if loss of regulation occurs.
