appear as shown in Figure 9-35.
Figure 9-35: Transient Menu
The MIL704 Transient screen has the following tests:
1 HIGH VOLTAGE
2 LOW VOLTAGE
3 HIGH FREQUENCY
4 LOW FREQUENCY
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.
HIGH VOLTAGE
This test will change the output voltage for the selected phase in the following sequence:
•
180V for 10 msec.
•
Linearly reduced to118V in 78msec.
•
Stay at 118V for 87msec before returning to 115V.
Prior to the test, a range change may take place if the power source is set for the low voltage
range.
The
←
key (backspace) will terminate the test at any time.
Note: A range change will result in momentary loss of power to the EUT. If this is not
acceptable, the power source must be left in high range at all times.
LOW VOLTAGE
This test will change the output voltage for the selected phase only in the following sequence:
•
80V for 10 msec.
•
Linearly increase to108V in 70msec.
•
Stay at 108V for 95msec before returning to 115V.
The
←
key (backspace) will terminate the test at any time.
HIGH FREQUENCY
This test will change the output frequency in the following sequence:
•
425Hz for 1 sec.
•
420Hz for 4 sec.
