AD595 - Thermocouple Amplifier - Cold Junction Compensation problem

Hi everyone,

 

I need to build a thermometer with thermocouple K using AD595 with cold juction compensation without additional second thermocouple K inside my device. I read whole AD595 datasheet but I can not find a proper complete schematic for cold jucntion compensation work mode of AD595. Probably this is a Figure 3 on page 4 of AD595 datasheet (PCB layout) - there is only one thermocouple (as I want to use) and 8 some electronics parts (as rectangles) but with no description and values.

Does anybody know how to proper connected AD595 in cold junction compensation work mode?

I will be very grateful for any help.

 

Best regards,

Jakub
