Figure 3 DC Voltage Circuit of RCA WV77. The common input jack of the meter connects to circuit common. It also connects through the parallel combination of a 1 meg ohm resistor and a 0.001 u f capacitor to chassis ground. The DC input jack connects through a 470 pf capacitor to the common jack. The DC input jack also connects to the plus DC and minus DC stators of switch S2D. The rotor of S2D connects to the 1.5 volt stator of S1A. The 1.5 volt stator connects through a 7 meg ohm resistor to the 5 volt stator. The 5 volt stator connects through a 2 meg ohm resistor to the 15 volt stator. The 15 volt stator connects through a 700 k ohm resistor to the 50 volt stator. The 50 volt stator connects through a 200 k ohm resistor to the 150 volt stator. The 150 volt stator connects through a 70 k ohm resistor to the 500 volt stator. The 500 volt stator connects through a 20 k ohm resistor to the 1500 volt stator. The 1500 volt stator connects through a 10 k ohm resistor to circuit common. Some of these resistors are also used in the AC voltage divider. They are wired to both S1A and S1B. The wiper of S1A is connected to both the plus DC and minus DC stators of S2F. The wiper of S2F connects to one end of the 3.3 meg ohm resistor that leads into the measurement circuit. This completes the verbal description of Figure 3.
