11. Option
–704F: MIL-STD 704 Rev A through F (MS704 mode)
11.1 General
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
–704F option as implemented on the Lx/Ls Series only supports AC power applications. DC
mode is not available on the Lx/Ls Series so no DC tests are provided in the
–704 option.
The Lx/Ls supports two different implementations of the MIL-STD 704. This chapter covers the
implementation that follows the test protocol handbook released with revision F of the standard.
This mode is selected by scrolling down in the APPLICATIONS menu to the MS704 entry and
pressing the ENTER key.
To test conform the legacy protocol instead, use the MIL704 mode from the APPLICATIONS
screen. (Refer to Chapter 9.)
Note: The MS704 mode was added with revision 0.99 firmware. If your Lx/Ls has an older
firmware revision, the
–704F option will not be available but MIL704 mode will be
available as long as the
–704 option was purchased. Check the AMETEK
programmable power website at
for available
firmware upgrades.
11.2 Initial Setup
Nominal parameters for the AC Power source are as follows:
Output Voltage
115V L-N or 230V L-N
Output Frequency
360 Hz to 800 Hz for all revisions.
60 Hz for revision F only.
Note: A setting outside these nominal values will disable the test and will prevent
access to the 704 Menu screens or execution of any test step. To execute all tests
for the 230V L-N, the power source must be capable of programming 360V RMS.
This requires the -EHV option output range pair (200/400V). If this option is not
installed, some tests will be skipped.
11.3 Test Revision
The MIL-STD 704 option is capable of performing all sub-sections of MIL-STD 704 revision A, B,
C, D, E or F. A selection is made available to specify the revision of standard to be applied to the
EUT.
The MIL704 option defaults to Revision E.
