AD541 2 use V*I short output issue

Category: Hardware
Product Number: AD5412

The customer use AD5412 as 4-20mA solution output, but when set full scale/ low scale current output . The output  can't output 20mA (17.5mA  Actual) and 4mA.

The CIRCUIT as below:

in the spec there's note that the Rset can improve the IOUT temperature drift performance, the customer just use general 1% accuarcy.

Boost Pin connect DIODE is ok or not?

 so please check circuit and advice the way to output 4-20mA full scale output. Thanks a lot.
