This test will change the output voltage for phase A and B to 122V and phase C to a voltage
lower by a value specified by an offset. Refer to Table 8-10 for the offset value and the
Frequency. The test will repeat with the same frequency and phase A and B volt is set to 100V
and phase C set to a higher voltage specified by the offset. The test will last 30 minutes. The
test will be repeated for a second Frequency if applicable. The test can be terminated at any
time.
The key (backspace) will terminate the test at any time.
