I have observed in field instrumentation work... I remove the fuse of an analog transmitter then it shows 7.75 kg/sq cm (which is practically wrong value)in DCS and when put the fuse it shows 0 in dcs. Then cheach the field transmitter termination and found moister. clean that and then it shows 1.1 kg/ sq cm which is right value. Please describe the above phenomenon.
