(2) 321 to 322 Measurement setting
Set the dead band of measurement display, and with or without of tidal current measurement.
321
Dead band of measurement
◆ 321 Measurement dead band
Set the dead band of measurement display.
By this setting, variation of less than this set value is
disregarded by voltage, current, active power, and reactive
power measurement display.
Setting range：0.0 to 2.0％ (0.1％ step)
Selection by ＋ and － , set value is updated by SET .
Default setting：0.0％ (None)
◆ 322 Tidal current measurement
By measurement of reactive power and a power factor,
0 (general measurement) or 1 (tidal current measurement
which was conscious of power transmission / power
receiving) can be selected.
Selection by ＋ and － , set value is updated by SET .
Default setting：0 (General measurement)

<Note> When used in a place where power transmission operation is performed (supply from the power generation side
to the power system side), the polarity (LEAD / LAG) of reactive power and power factor measurement during
power transmission changes depending on the power flow measurement setting.
However, the meter display is LEAD on the left and LAG on the right.
