  i have connected my ic(AD 595)and thermo couple as  suggested in data sheet. and i am measuring voltage signal through NI daq card. i am gettting good result for temprature greature than 35 degree centi. but when temprature goes below 35 . my ic is giving constant 350 milivolt signal it does not go below. means am able to measure only minimum temp 35 degree. my room temp is 20 degree . and one more thing should we sort pin 8 and 9 or not. if not than what to do with pin 9.

i also did not used any register to ground thermocouple negative pin. i directly grounded it without using any resistance



thank you
