DC OUT

In order to run this test, do not connect any load impedance.

Adjust the signal generator to deliver a signal with a frequency below 5Hz, and select the 3V scale
output level.

Connect the oscilloscope to the unit's output, 5V/div vertical scale, 20ms/div time base. Use a 10x
attenuating test probe.

Turn on the signal generator. Increase its output level untill the thyristor starts actuating, and the
observed signal becomes the typical sawed sine wave. Use the oscilloscope's memory bank in order
to observe carefully this fact.
