C H A P T E R C

V= (Ta1 - Ta2) / (Td1 - Td2), and U = Ta1 - (Td1 * V) Then C1n and C2n can be determined by the following:

C1n = U + (V * C1) and C2n = V * C2

6Replace C1 with C1n by selecting the C1 parameter and entering the new C1n value. Replace C2 with C2n by selecting the C2 parameter and entering the new C2n value.
