DC Current. Measure the DC current output of the rectifier with a handheld
multimeter on the mV scale. Measure mV from N2 to N3. Multiply the indicated reading
by the appropriate multiplication factor (Figure 5-3). One of three conditions may exist:
the current may be near zero (proceed to paragraph 5-2.2.1), near half of normal
(proceed to paragraph 5-2.2.2), or be near normal (proceed to paragraph 5-2.2.3).
