Scalling Error in Analog Module via LM90

Hi friends;
I purchased a new analog module ALG 223. I connect the transmitter 0 to 87 PSIG. Set the configration as follows
low=0000
high=32000
at 4 mA the counts are +0000 and at 6.08 mA counts are 4136 (unable to apply 20 mA right now)
Now i attached a image which i apply for scalling according to following formula
EU = ((EUSpan x (DATA - DataOffset))/DataSpan) + EUOffset
ProcessValue = EU / FACTOR
Scalling applied 0 image starts for done scalling Variable RAW have counts from %AI.
at 6.08 mA the reading should be 11. somthing but it shows 14.0 a three psi error.
I am confuse to done it please guide me how i get and which block step by step i apply to get the right value.
I use the mathmetical equation as
FACTOR = 10
Data @ 4 mA = 0000
Data @ 20 mA = 32000
DataOffset = 32000
DataSpan = 32000
EUOffset = 0 x 10 = 0
EUSpan = (87 - 0) x 10 = 870
DATA = 4136 counts from %AI
EU = ((870 x (counts - 000)) / 32000) + 0
But a guy use the following method and i am confuse how he calculate
FACTOR = 10
Data @ 4 mA = 6240 // this one ???????
Data @ 20 mA = 31208 // this one???????
DataOffset = 6240
DataSpan = 31208 - 6240 = 24968
EUOffset = 0 x 10 = 0
EUSpan = (60 - 0) x 10 = 600
DATA = 18975
EU = ((600 x (18975 - 6240)) / 24968) + 0 = 306
Process Value = 306 / 10 = 30.6 psig

Secondly for every transmitter the scalling is diffrent?
please i need a explanation for understanding
Hope you guys help me to considered my example
Regards

In rung 14 why did you divide by 25,600 rather than 32000?

You need the factor of 10 because by your choice of 870 for your EU span you selected tenths of a PSI for units.

Sir;
Oh sorry i do it now it value is 11.2 PSi.
Sir i want to ask where this type of following calculation is used?
Data @ 4 mA = 6240 // this one ???????
Data @ 20 mA = 31208 // this one???????
DataOffset = 6240
DataSpan = 31208 - 6240 = 24968
Secondly if i use in enhansed mode and set -2000 to 32000 then the logic which i applied working?
Sir u see images i want to ask that i do correct work or it replace by a short logic? Please guide me
Regards
