MX Series 265
This test requires 180-volt output voltage. If the power source is set at the low
voltage range, the high voltage range will be selected before the test starts. At
the end of the test the AC source will be switched back to the low range.
The output voltage will surge to 180 volts for 100 ms. followed by drop to 148
volts for 1 sec before it returns to 115 volts. The ← key (backspace) will
terminate the test at any time.
FREQUENCY TRANSIENTS (GROUP 1 ONLY)
