VOLT MIN
This test will set the voltage and frequency to levels defined by Table 9-12 for 5 minutes. The test will be
repeated for Group1 only as indicated in Table 9-12. All Groups will repeat the test using Table 9-12 for
the voltage setting and Table 9-11 for the frequency setting. The

key (backspace) will terminate the
test at any time.
VOLT UNBALANCE
This test applies only to RTCA2 standard.
Standard/Group A(CF) A(NF) A(WF)
Voltage offset 6 6 8
Frequency 400 360/650 360/800
Table 9-13: Abnormal Voltage Unbalance
This test will change the output voltage for phase A and B to 134V and phase C to a voltage lower by a
value specified by an offset. Refer to Table 9-13 for the offset value and the Frequency. The test will
repeat with the same frequency and phase A and B volt is set to 97V and phase C set to a higher
voltage specified by the offset. The test will last 5 minutes. The test will be repeated for a second
Frequency if applicable. Additional test for A(CF) category is applied with phase A and voltage set at
122V and phase C at 116V. The frequency is set at 430V. The test is repeated with the same
frequency but phase A and B are set at 100V and phase C set at 106V. Both tests are repeated for
370Hz.The test can be terminated at any time. The

key (backspace) will terminate the test at any
time.
VOLT UNDER
This test will drop the output voltage from 115 volts to 60 volts for 7 seconds.
VOLT SURGE
This test requires 180 volt output voltage. If the power source is set at the low voltage range, the high
voltage range will be selected before the test starts. At the end of the test the AC source will be
switched back to the low range.
Note: To avoid switching to the high voltage range which provides only half the current of the low
voltage range, the -EHV option range pair must be installed (200/400V).
The output voltage will surge to 180 volts for 100 ms. followed by drop to 148 volts for 1 sec before it
returns to 115 volts. The

key (backspace) will terminate the test at any time.
