Divider Circuit Offset Adjustment Procedure
1. Set each trimmer pot to 0V on the wiper.
2. Connect V
3.
4. Return V
5. Connect V
Notice that as the input to VX and VZ gets closer to zero (an
illegal state) the system noise will predominate so much that
an integrating voltmeter will be very helpful.
