11.8 MS704 Operation Using the LxGui Software
The LxGui supplied with the Lx/Ls Series AC power sources can be used to operate the MS704
option. The LxGui detects the presence of this option and enables access to the relevant
operating screens. If you are unable to access the MS704 option screens from within the LxGui,
you do not have the -704F option (MS704) installed or the firmware in your unit pre-dates release
of the MS704 version of this option. In that case, contact AMETEK Programmable Power for
upgrade information. (

The information on use of the LxGui with the MS704 option is also contained in the on-line help
file of the LxGui program.
Note: For Ls Series AC sources without the –ADV option installed, the harmonic
analysis and waveform acquisition functions described in this section are not
available. Contact
[email protected] to upgrade the Ls AC Source
with the –ADV option. The MIL-STD 704 stimulus can still be run however.
11.8.1 Steady State Settings
To access the MS704 test screen, the steady state settings of the Lx/Ls AC source must meet
the following conditions:
Parameter Setting Notes
Output voltage for all phases: 115Vrms or 230Vrms Line to Neutral.
Frequency: Between 360 and 800 Hz
or 60 Hz.
Phase Rotations: A = 0°, B = 240°, C = 120° Three phase mode only.
If one or more conditions is not met, the MS704 screen cannot be opened but instead an error
message indicated the above conditions must be met will be displayed. The state of the output
relay (open or closed) is not important. If needed, the output relay will be closed when the user
starts a test.
The Mil-Std 704 tests can be selected from the LxGui toolbar or menu. There is a separate
toolbar button for
–704 and –704F options or an individual menu entry for each option. If the
corresponding options are installed, the toolbar button and menu entry will be active.
