4 electrode condcutivity evaluation using  EVAL-CN0359-EB1Z  by simulated resistance

 

Wish to know when  and how "sensor  incorrect  error" will be reported,during resistance simulation of 4 electrode conductivity?

4 electrode is simulated by connecting  3 different resistances,R1,R2,R3 .

    1)   R1-wire resistance is connected - between terminal 1 and 2  of j5.

    2)  R2-sense resistance is connected -between terminals 2 and 3 of  j5.   

    3)  R3-wire resistance is connected -between terminal 3 and 4 of j5.   

3. If sense resistance R2 is 100K,what are the possible maximum permited values of R1 and     R3,before "sensor incorrect error" reported?

4. Where (in hardware/firmware ) "sensor  incorrect  error"  comparison is taking place please explain how?
