indicated in numbered boxes, and described in detail here below:
(1) Insert the multimeter probes between pins 1 (signal) and 2 on the CN27 patch cord. With the
brush far from the sensor you should get a reading of approximately 5 Vdc while with the
brush close to the sensor you should get a reading of approximately 0 Vdc.
(2) Insert the multimeter probes between pins 1 (signal) and 2 on the CN4 connector on the Bio
servo board. With the brush far from the sensor you should get a reading of approximately 5
Vdc while with the brush close to the sensor you should get a reading of approximately 0 Vdc.
(3) Insert the multimeter probes between pins 17 (signal) and 1 on the CN7 connector on the Bio
servo board. With the brush far from the sensor you should get a reading of approximately 5
Vdc while with the brush close to the sensor you should get a reading of approximately 0 Vdc.
(4) Insert the multimeter probes between pins 3 (signal) of the K5 and 1 of the K4 connector on
the CPU board. With the brush far from the sensor you should get a reading of approximately
5 Vdc while with the brush close to the sensor you should get a reading of approximately 0
Vdc.
On Chest Press and Leg Press, the BS-6/2 cable is divided into 2 parts through the
