Thank you both for your explanation. This has now answered my question, can often get quite confusing when there is so much instrumentation knowledge to be learnt, thank you.
Could someone give me a proper definition of the two for a temperature transmitter. I know how a thermocouple works however calibrating it I'm not to sure on. Could you correct me if I'm wrong but i think zero error is when your expected zero is not reading zero and is either higher or lower...
