LOW VOLTAGE
This test will change the output voltage for the selected phase in the following sequence:
1. 28V System
•
18V for 15 msec.
•
Linearly increase to 22V in 85msec.
•
Stay at 22V for 75msec before returning to 28V.
2. 270V System
•
200V for 10 msec.
•
Linearly increase to 250V in 30msec.
•
Stay at 250V for 135msec before returning to 270V.
The ← key (backspace) will terminate the test at any time.
