VOLTAGE SURGE
This test requires 160V 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 8-5: Normal VoltageSurge Sequence
The output voltage will follow the sequence in Table 8-5. The above sequence will repeat itself
three times. Each repeat will start from sequence two. RTCA and Group 1 will run at 400 Hz.
Group 2 and A(NF) will run at 360 Hz and 650 Hz. Group 3 and A(WF) will run at 360Hz and
800Hz. The frequency will return to the nominal setting when the test is completed. The

key
(backspace) will terminate the test at any time.
