VOLT UNBALANCE
This test will change the output voltage for the selected phase only in the following sequence:

112V for 1 minute.

118V for 1 minute.

115V for 1 minute.
The test will be repeated on three phase systems to include all three phases if the coupling is set to all.
The

key (backspace) will terminate the test at any time.
PHASE DIFFERENCE
This test applies to three phase systems only. The phase angle for the selected phase will
change relative to phase A in the following sequence:
If phase B is selected:

236

for 1 minute.

244

for 1 minute.

240

for 1 minute.
If phase C is selected:

116

for 1 minute.

124

for 1 minute.

120

for 1 minute
VOLTAGE MODULATION
