Settings

Only values 1-3 of the parameter GlobalBaseSel should normally be
used. The values 1-3 refer to the global base value groups Phase Grp
1, Phase Grp 2 and Phase Grp 3 correspondingly (BASEPH1,
BASEPH2 and BASEPH3 in PCM600). The selection affects the
actual limit for frequency calculation set by MinValFreqMeas which
by default is 10% of the Voltage base Val PP in the selected group.
The values 4-6 refer to Residual Grp 1, Residual Grp 2 and Residual
Grp 3 (BASERES1, BASERES2 and BASERES3 in PCM600)
correspondingly and they are typically not to be used in this
connection.

Even if the AnalogInputType setting of a SMAI block is set to
Current, the MinValFreqMeas setting is still visible. This means that
the minimum level for current amplitude is based on Voltage base Val
PP. For example, if Voltage base Val PP is 20000, the minimum
amplitude for current is 20000 * 10% = 2000. This has practical affect
