The voltage gradually decays with time to 125 volt b he following
V = 2. or ≤ 6.925
Stay at 125V for 93 seconds before returning to 115V.
For 60Hz only:
• 180V for 3.34msec
1.947
• 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.
