Unless otherwise specified for the power supply at the time of test, use the constant voltage power supply. When testing the available time for load short-circuit and output noise voltage, use the specified transformer as shown right. The output noise voltage is the peak value on the mean value indicating rms reading (VTVM), and should not involve impulse noise.
