Connect the SCR block circuit in Figure 2-10, and place CM switch 6 in the ON position. With the oscilloscope monitoring the anode of Q1 and the multimeter across R4, press S1. From your measurements, you determine that a. the gate is open. b. the anode to cathode is shorted. c. the SCR is working normally. d. R4 decreased in value.
