3. Next, find m & b:

X1

=

0 VDC

ç minimum expected input

=

0 A/D counts

at Transducer minimum output

X2

=

2.0000 VDC

ç maximum allowable input

=

20000 A/D counts

at Transducer maximum output

Y1

=

20.00 %RH

ç choose decimal point = 2

=2000 display counts

Y2

=

90.00 %RH

ç keep decimal point = 2

=

9000 display counts

[Desired % RH resolution 2 places to right

m

=

(Y1 - Y2) / (X1 - X2)

of the decimal point (.01% RH)]

=(2000 - 9000) / (0 - 20,000)

=0.35000

b = Y2 - (m * X2)

=9000 - (0.350 * 20,000)

=002000
