The above tests can be selected by scrolling to the highlighted selection using the up and down key
and the ENTER key to start the selected test.
VOLT MIN
This test will change the output voltage from 28V or 14V to 20.5V or 10V. The test will last for 30
minutes. The ← key (backspace) will terminate the test at any time.
VOLT MAX
This test will change the output voltage from 28V or 14V to 32.2V or 16V. The test will last for 30
minutes. The ← key (backspace) will terminate the test at any time.
VOLT LOW
This test applies for category B equipment.
This test will change the output voltage to the voltage minimum for one minute. The voltage will decay
linearly to zero voltage in a ten minute period before returning to its nominal voltage.
VOLT DROP
This test will change the output to 12V from 28V or to 6V from 14V for seven seconds. The output
voltage will return to nominal voltage after seven seconds.

10. Option -704: MIL-STD 704 Rev D & E (MIL704 Mode)
10.1 General
Option –704 includes a firmware implementation for Mil-Std 704 revision D and E and a short version
of r i MIL704 handbook, the GUI based software
imp e vionics tests are covered by a separate Avionics
Software Manual, CI P/N 4994-971, which is distributed on the same CD as this manual.
This user manual assumes that the user is familiar with the text of the relevant MIL-STD 704, test
standard. No attempt is made to explain or elaborate on the actual test specification. The–704 option
supports both AC and DC power applications.
Test Execution Considerations
Several of the MIL-STD 704 test steps take considerable time to execute. Tests in progress may be
