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.

The output voltage will follow the sequence in Table 9-5. 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 BACK key (backspace)
will terminate the test at any time.
