8-30. 1 V de Reference Offset Error Measurement. Since
the 1 V dc full scale reference was derived by dividing the
internal reference by the precision 'ten-to-one divider, a
separate offset Error measurement is made to include any
offsets present in the ten-to-one divider and associated @
circuitry. Figure 8-12 illustrates the circuit configuration
