10.5 Front Panel Operation MIL704
To perform a test from the keyboard, from the MENU 2 screen, select the APPLICATIONS screen.
The APPLICATIONS screen will appear as shown in Figure 10-1.

Scroll to the MIL-STD-704 entry using the up and down cursor keys. Press the ENTER key to select
the MIL704 main menu. One of the screens will appear as shown in.
Note: The user has to turn on the Output relay before starting a test and set the steady state setup for
the test. NOM FREQ must be set to match the desired steady state frequency. All MIL704 revisions
will accept 400Hz as a nominal frequency. Revision F only will accept 60Hz and VFREQ.
