14. the procedure until zero and span are adjusted correctly Now the zero and masibus Span adjustment of the output 1 card are calibrated Similarly calibrate output 2 of the unit Trim pots are identified by Z for zero and S for span calibration for both output separately For checking the Linearity takes reading in steps of 25 Repeat the same procedure for calibrating the other output Similarly for the potentiometric input type the output has to be calibrated at two points Zero Desired O P value at minimum I P value at minimum Input value and Span Desired O P value at maximum I P value at full scale value Variable Resistance Box can be used for calibration Note For FOP calibrate output 3 amp 4 of the unit as per above calibration procedure 5 0 APPLICATION Why Is Isolation So Important In most processes there are pieces of electronic measurement and control equipment from many different manufactures The signals from these instruments are interconnected to each other and to sensors transducers and output devices connected in the process loop In any such measurement and control system there are several problems that are likely to occur all of which can be solved by incorporating the appropriate isolation between signals APPLICATION AREA A typical application could be where the Signal has to be distributed for indication on local panel field control room main control room and DCS system
