Good Evening ,
I’m getting ready to integrate a Mettler Toledo IND 570 into a ControlLogix PLC , Analog 4-20 ma input card 1756-IF16 . I’m trying to use a Fluke 705 Loop Calibrator to get my scale where I want it going into the 1756-IF16 , and it just stays at 10.36 .
On the calibrator I have the black lead on RTN ( 24 Vdc common ) and the Red lead going in on the analog input IN-11.
When nothing is connected in the input I get 12.5 .
What in the world am I doing wrong ? I don’t have any load cells hooked up
to the IND 570 yet . I just want my input to read 4 ma , 8 ma , 16 ma and 20 ma, from the calibrator . I got to be doing something wrong .
Thanks so much in advance ,
