Table 9-11: Abnormal Voltage Maximum
This test will set the voltage and frequency to levels defined by Figure 9-10 for 5 minutes. The
test will be repeated for Group1 only as indicated in Table 9-10 for voltage and Table 9-11 for
frequency. All Groups will repeat the test using Table 9-10 for the voltage setting and Table 9-
10 or Table 9-11for the frequency setting. The ← key (backspace) will terminate the test at any
time.
VOLT MIN
This test will set the voltage and frequency to levels defined by Table 9-11 for 5 minutes. The test
will be repeated for Group1 only as indicated in Table 9-11. All Groups will repeat the test using
Table 9-11 for the voltage setting and Table 9-10 for the frequency setting. 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.
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.
