<Width of sensitivity adjustment>
66.7% to150% (ADJ5 to ADJ0=000001=66.7%, ADJ5 to ADJ0 = 100001 = 150%)
<Sensitivity Calculation>
 Decreasing Sensitivity (ADJ5=0)
Sn=16*ADJ4 + 8*ADJ3 + 4*ADJ2 + 2*ADJ1 + ADJ0
S=2*Sn / (2*Sn+1)
(Example) ADJ5 to ADJ0 = 001010, Sn=8+2=10, S=20/21=0.952. The sensitivity is 95.2%
 Increasing Sensitivity (ADJ5=1)
Sn =16*ADJ4 + 8*ADJ3 + 4*ADJ2 + 2*ADJ1 + ADJ0
S=(2*Sn+1) / 2*Sn
(Example) ADJ5 to ADJ0=100110, Sn=4+2=6, S=13/12=1.083. The sensitivity is 108.3%.
