Error in detection temperature with INA826

Dear sir/madam,

     I designed a temperature detection circuit with INA826. The components on the circuit are selected by RTD_Linearization_v7.xls downloaded from TI.com. When I connected Pt100 to the circuit about 150ohm at 140 degree, the voltage output from the circuit is only 2.67*(3.3/(10+3.3))V rather than 6.7*(3.3/(10+3.3))V. The circuit is enclosed.

   I am looking forward to your reply as soon as possible.

Regards,

Qian.Miao
