VOLT MAX
This test will change the output voltage from 28V or 14V to 30.3V or 15.1V. The test will last for
30 minutes. The ← (backspace) will terminate the test at any time.
VOLT UNDER
This test applies to category Z and 28 volt category B equipment. The output voltage will drop to
10 volts and will ramp up at a rate of 0.15 volt/sec for the US standard and at a rate of 0.30
volt/sec for EUROCAE standard for 30 seconds before it returns to nominal value.
VOLT SURGE
This test will surge and sag the voltage to a
seconds between transients. The test is repeated three times.
