
Stay at 122V for 8 seconds before returning to 115V.
Note: Prior to the test, a voltage range change may take place if the power source is set for the
low voltage range. This will cause the EUT to loose power momentarily. If this is not acceptable,
the power source must be left in high range at all times.
The

key (backspace) will terminate the test at any time.
UNDER VOLTAGE
This test will change the output voltage for the selected phase in the following sequence:
For 400Hz and VFREQ:

0V for 7 seconds.

100V for 93 seconds.
For 60Hz only

0V for 2 seconds.

100V for 8 seconds.
The

key (backspace) will terminate the test at any time.
OVER FREQUENCY
This test will change the output frequency in the sequence shown in Table 9-15 before returning
to the steady state frequency.
The

key (backspace) will terminate the test at any time.
