SELECTOR SWITCH CONTINUITY AND RESISTANCE
TEST
1.
Connect multimeter (1), set to RX1, to pins A and
L of selector switch (2).
2.
Rotate selector switch knob (3) through all dial
positions. Check multimeter (1). Multimeter
shall indicate continuity at all switch positions.
Disconnect multimeter.
3.
Connect multimeter (1), set to RX1, to pins A
and D of selector switch (2). Repeat step 2.
Disconnect multimeter.
4.
Connect multimeter (1) set to RX1 to pin A and
case ground (4) (receptacle shell). Repeat step
2. Disconnect multimeter.
5.
Set selector switch knob (3) to SCAN.
6.
Connect multimeter (1), set to RX 10,000 to
pins N to S of switch (2). Check multimeter (1).
Multimeter shall indicate between 9.975 and
11.025 K ohm.
7.
Repeat step 6 between pins N to R, N to G, N to
H, and N to F of switch (2). Then go to step 8.
