VOLTAGE SURGE
This test requires 160-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 power source will be switched back to the low range
automatically

Table 9-4: Normal VoltageSurge Sequence
The output voltage will follow the sequence in Table 9-4. The above sequence
will repeat itself three times. Each repeat will start from sequence two. US and
Group 1 will run at 400 Hz. Group 2 and Group 3 will run at 360 Hz and 650 Hz
for Group 2 and 800 Hz for Group 3. The frequency will return to the nominal
setting when the test is completed. The ← key (backspace) will terminate the
test at any time.
