1.   Remove the cover from TCDA module. 

 

2.  Connect thermocouple to terminal blocks T1+ and T1- as 

described in chapter 3 (T2+ and T2- for channel 2). 

3.    
4.   Plug power supply in 2.5mm power jack and plug supply into 

wall outlet. 
 

5.   Adjust P2 so that there is Voff on pin 6 or 7 of U1 (adjust P3 so 

there is Voff on pin 6 or 7 of U3 for channel 2). 
 

6. 

 Place the thermocouple in a substance with a known 

temperature.  Adjust P1 so that the voltage on DB-25 pin 8 is 
equal to the calculated Vout (adjust P4 so that the voltage on 
DB-25 pin 9 is equal to the calculated Vout for channel 2).
